Hmmm i tried pinging my external ip (cause im at university now) and I'm getting a request timeout. I'm almost certain thats my correct external IP. When I get home i could try pinging the internal but that will have to wait. On the topic of DHCP Yes I have a DLINK wireless router (fairly new). Should I be able to ping my external from the terminals at school? Or do I have a problem?
