My little home network have five computers connected to a LAN hub and one of them is connected to internet with ADSL connection. All other computers then shares the internet from that computer (including my one). The server computer is running win2k-server, and my computer is running Win XP.
But when I try to send files using ICQ or MSN, I couldnt do so, the programe said something about firewall blocking. I then tried every option to stop the firewall and opening up ports, but the problem still remains...
Is anyone having the same problem? and knew how to solve it?
your not making any sence. the computer running ics is just in the place of a router. if the modem is running dhcp and nat then it has a built in router. well internal network router anyway, since a dsl modem is infact a router. and a SWITCH does not have a wan port.
my computer is so fast, it completes an endless loop in less than 4 seconds!
I don't have any real experience with those specific programs but here are my thoughts just in case you haven't had them yourself already:
If you can chat with ICQ and/or MSN then it's probably not an ICS problem, I'd take a closer look at WinXP's built in firewall or any firewall that might exist at the other end of the file transfer (unless of course it happens no matter who you're sendin em to). In fact if XP's firewall is on I'd just plain shut it off and get ZoneAlarm or BlackIce instead.
Also check the program's settings themselves to see if you can map specific ports for file transfer's and such, many programs of that ilk give you options to pass through a firewall/NAT. I don't know if ICS lets you map ports or not but it would be nice if it did.
Hardware: the parts of a computer that can be kicked.
Sorry but you are trying to the impossible as far as I know.
You can not forward ports through ICS even if you forward them through the modem. You can not forward ports through 2 devices. Whether it be a modem and router,modem and ICS on comp or two routers.
When first replying to your post I assumed you had a ethernet modem. Since you are running a USB modem none of the above applies. You are out of luck nless your modem also has a ethernet(RJ45) port.
Your best solution would be a Ethernet(RJ45) modem and the linksys switch.
