Here are some tips in no particular order that come up in the forum that we have solutions for. In these examples, we'll assume the following:

Here is What I've got so far (last updated 05/14/01):

I've posted most of these solutions on, but their forum software sucks... Posts get lost, the forum changes it's version/look, other posts never make it, etc. I know i'm not the only one who thinks that practicallynetworked uses THE worst forum software ever!!!! Some of these solutions have come from other users on practicallynetworked too. I'll try to give credit where credit is due, but the main point of this page is to help people and use it as a reference point since our posts keep getting lost...

Having said that... A few questions get asked over-and-over on the forums. I've posted solutions over-and-over too. BUT, the forum continuously looses my posts... VERY frustrating...

So, here are a few tricks/solutions/workarounds to the SMC/AMIT routers. This page is very informal, and a quick-fix. I've got a BS in Electical Engineering (minors in computer science and mathematics), and am an IS manager for a Chemical Analysis company. I'm NOT a speller nor was I ever an english major! heeh! Perhaps sometime i'll put more effort into this, spell checker, etc., but more than likely not! I'd rather put more effort into the routers and their issues! heeh! -jeremy

The "admin trick" refers to accessing the router's administation pages while trying to prevent the router from locking up. The AMIT based routers have a tendancy to lockup (or timeout) while accessing the router's configuration pages typically requiring a reboot of the router by it's power switch. A lot of times, it freaks out while trying to load one of the 3 framed pages. Many times you can avoid this by accessing the configuration pages in a round-about way. By visiting ONE of the frames rather than the entire administrative page, you can help to avoid the lockup or timeout. To access the admin pages in this manner, add the suffix /menu.htm to the url you use to access your administration pages. It should look something like In my setup it would be:
NOTE: you may or may not need the :88, i've found that some firmware's like it others don't care...

The pages will look the same, except broken out rather than contained in frames. Not as clean as the original framed pages, but better than a lockup!

Here is what I posted a while back on alt.icq (under my newsgroup alias 'So Polite' to avoid spam) and on the practicallynetworked:

hi all! 'So Polite' here again... i decided to post the fix for you now that i have played w/ it for a while... icq's web site still says it isn't possible to receive files (or chat or basically establish a direct connection) behind hardware firewalls using NAT.. i'm here to tell you that you can (and i do..) WITHOUT DMZing it...

at work i use a cisco router w/ dsl and win2k. at home i use a smc barrade router/switch and win98se. same configurations on both ends (meaning same configs on the routers and OS's), just a little different on how you do those configurations. i'll be real nice and spell it out for this setup so hopefully someone will benefit from it!

here are the steps:
WHAT IT REQUIRES - brief overview
SETUP ICQ - icq settings
CISCO 1400 EXAMPLE - how to map ports on a cisco 1400 router
SMC BARRACADE EXAMPLE - how to map ports on a smc barracade router
GENERAL NOTES - self explanitory!

you have to map 5 ports to the machine(s) you want to receive files on... 4 doesn't work, 5 does. if you use less than 5, you'll get a 'can't send files on listening tcp port' or something like that. i can't receive 2 files at once, i'd imagine it would take 10 port maps. since this wasn't of interest to me, i didn't test it out... i only need one direct connection at a time... then you tell icq that you are using a firewall, and those specific 5 mapped ports. then, enjoy! you can receive files! (or chat, or whatever)

in the icq configuration (the same for win98 or win2k) (oh, and i'm using the 2000b version) open icq, click the ICQ button, and choose preferences. click the 'connections' selection toward the left, then the 'server' tab. choose 'using a firewall' and 'not using a proxy'.

click the 'user' tab, and choose 'not using a proxy' and 'use the following tcp listen port for incoming event'. pick 5 ports in a row that you want to use (remember them as you will be mapping those ports latter...) for this example i'll choose 12000-12004. keep the numbers that you choose high so that there is less likely of a chance that you will mess up another program. so since i chose 12000-12004, i would enter 'from 12000' and 'to 120045'.

click 'apply' and you will then have to restart icq for the changes to go into effect. you are now done. you basically just told icq that you are using a firewall w/out a proxy, and forced icq into using 5 ports instead of their default million random ports... this is what lets you use icq behind a proxy w/out DMXing it... (taking out the randomness that is...)

the cisco 1400 is basically a router designed for dsl use. it is pretty high end as 'dsl modems' go and has a lot of firewall capabilities. i do configurations from the command prompt, and will assume that you know how to do that. if not, you're on yer own, you'll have to look that up! but assuming you know how to set up yer cisco from the command prompt, here is how you map the 5 ports to the private ip (you would pick the private ip address of whichever computer you want to use icq from) (this is all one line below):

ip nat inside source static tcp 12000 12000 extendable

all you have to do is replace w/ yer private ip address, and w/ yer public ip address (of the cisco). it tells the cisco that anything coming to the cisco ( on port 12000, send it to on port 12000. repeat this w/ 12001-12004 and you will have mapped all 5 ports. and in case you are wondering, is NOT my ip address! heehee! write mem yer changes, and you are all set to receive files! woohoo!

i own a smc 4 port 10/100 barracade router/switch at home. this is a cable modem or dsl router w/ 4 10/100 switched ports built in. i like it a lot and it also has a analog modem port AND print server built in! i think they are going for about $100 online after rebate. they only think i would replace it w/ would be their 8 port version!! at any rate, i think it too has a command line interface, but for it i just use the web configuration interface. so, lets map our 5 ports on the barracade...
1) go to the router's configuration page via a browser. it would look something like or whatever you have set yer barracade's ip address to.
2) log in to the router in the left pane (Default password is "admin" w/out the quotes.
3) after you log in, click the 'virtual server' link on the left.
4) you now see a few fields replicated 10 times. lets map a port.. on any one of the ID's, fill in the 'service port' w/ '12000', the 'Server IP' w/ '', and check the 'enable' box. you have just told the barracade to send all traffic from port 12000 to the private ip address (of the icq computer)
5) repeat step 4 w/ the other ports (12001-12004)
6) click the 'save' button down below, and then 'reboot' yer router w/ the 'reboot' button.
congrats, you are all ready to receive files!!!

well, i hope this novel is usefull to someone. it took my friend and i about 20 minutes to setup what icq says you can't... (or at least at the time says you can't.. wouldn't be surprised if they say you can now.. or perhaps after reading this? heehee!) as i said, this will let me make 1 recieve connection at a time.. if you want more, you'll probably have to map 5 more ports. but i havn't tried it, i have no need for it. enjoy!

Yes, and yes! You can play Quake 3 or Quake 3 Team Arena w/ just the default settings on the router. You can even have multiple clients behind the router w/ no setting changes. (Personally I've had as many as 3 clients behind my router.)
To HOST a game will require a port map. By default, this is port 27960. Just map this port in the 'Virtual Server' settings to your Quake server, and you are good to go. NOTE: if you are not using port 27960, or are hosting multiple games (then you have too good of a connection to be using a AMIT router, go get yerself something better! heeh, just kiddin of course, just a little jealous if you can host multiple games, i cannot even host one game w/ more than 6 people on my cable modem, heeh!) then you will need to map that non-default port or the multiple ports being used for multiple Quake 3 servers.

This were the steps I wrote up for Sam in the forum on how to get Netmeeting
working. Feel free to use them/modify them for your FAQ page. I have seen
people talk about setting up ports to allow Netmeeting but the AMIT BIOS
updates readme's suggest you must use DMZ for Netmeeting.

1. Login to the router setup page by going to in your
browser (adjust if you changed the router's IP address)

2. Select "Misc items" from the menu on the left

3. The top line is "IP Address of DMZ Host". Enter the last digits of the
IP address of the machine on from which you want to do netmeeting.
(in our example cases it would be 10 for You can find
the IP address by entering "winipcfg /all" into the RUN dialog (click START
then RUN) assuming you have a Windows 9x system.

4. Click on the enable box to the right of that line so a tick or check

5. The coloured triangle at the beginning of the line will change colour to
note a change has occurred. Then click on the SAVE button at the bottom of
the screen.

6. You will get a message about some changes don't take effect until after a
reboot. Click on the REBOOT button that will appear at the bottom of the

7. After the reboot log back in (if necessary can't remember) and go to
items again. Make sure the setting is what you want.

8. Logout from the router.

9. Power off the router and wait 5 seconds and then power it on again.

10. Logon again and make sure you get an IP address again (if your ISP uses
DHCP) if you have static should be OK to use. Just make sure it came back up

11. Test you Internet access by going to a web page. If OK then go to and follow the Shields Up links. Test your system for security
holes by doing both tests (Test My Shields and Probe My Ports). If you don't
have wide open security problems you should be OK.

12. Try your Netmeeting. If people are calling you they may need to call to
your public (ISP provided) IP address rather than finding you via your
e-mail address and an ils server. If you are initiating the call you may
also need to use the other person's IP address - depends on their setup and
whether they use a router/firewall or not.

13. After Netmeeting I suggest you go back into the router config and
the tick/check mark from the enable box for the DMZ address. Then reboot to
turn off the DMZ access. This will make you fully secure again. You can
leave the IP address and just turn on and off with the enable box.

14. If you don't want to turn DMZ on and off make sure you get ZoneAlarm
from and install it. ZoneAlarm can protect your DMZ PC but
understands how Netmeeting works and allows it to operate normally. Sort of
defeats having a router if you do this but the added protection of knowing
which apps talk out from your PC to the Internet is not a bad thing.
