well 1 and 2 i have definitely done. not sure how to go to the remaining 7 steps though. the thing is on firewall. i have Windows Firewall but according to F'Nar when i was chatting with him on MIRC Help he said that wouldn't matter if it was on or off. which is true because as i mentioned before i had it on before i had the wireless modem/router put in and it worked fine. But the router has it's own firewall built in i understand but i don't know if it's that or not. no one seems to understand how to turn it off if it is that so... i don't know. by the way you keep saying "Router > etc etc" what do you mean? i don't have a folder or even an option in control panel called Router.
Windows > START > RUN > CMD > IPCONFIG
The default gateway is the routers IP
Run internet explorer and enter the gateway IP in the address bar
This should take you to the linksys wcg200 settings web interface page (in the router) and this should look like the pages shown
here.
If these pages are not present it is becuase comecast have flashed the router with there own firmware, this may limit/destroy any chance you have to doing whats needed, you could attempt to flash it with the correct firmware from linksys, but dont count on it!
I had a ssumed you had a normal linksys modem as you did not state before that the portforward websites instructions for the router did not match.
if "the thing is on firewall" refered to a router firewall then it liekly needs to be off, portforward states the linksys needs it off.
********* TURN WINDOWS FIRE WALL OFF **********
Your got a router its got firewalling built in by the share nature it doesnt forward ports unless u tell it to, that is beyuond any actual firewalling codeware in it.
And if u dont want to turn it off then Xp firewall needs the mirc dcc ports pinhold through the fire wall.
I wouldnt be suprised if the problem has been that windows firewall was on and blocked the ports.
