I am running Linux, my wife runs Windows XP- today I went into my router (dlink ebr2310) and forwarded a port (6346) to enable an application to run properly. It solved my problem, but then my wife was unable to connect to the internet. I have a cable system and the two computers connect to the cable modem through my router. I can't understand why changes I made in the router for my system prevented her from connecting to the internet ?? I had to go into the router again and disable port forwarding for my computer.
