If anyone has any ideas on this I'd be really grateful - it's driving me round the bend!
I have a LAN in my house, connected to the internet via a DSL router using NAT and DHCP. The problem is my computer appears to have an imaginary firewall! I can access the net, etc., as can all the other computers on the network. I can ping my computer's ip and other computers, but they can't ping me.
First thought: I must have a firewall - however, I've disabled windows firewall (XP SP2) and turned off ZoneAlarm but still nothing. This is really annoying as I'm trying to run a web server with IIS, which is inaccessible at the moment, presumable for the same reason.
Please help!
