Hi Dave, You might be half correct! Things i have found with the help of my XP is that it assigned a default gateway, back to foxboard i added the default gateway (and seems "logic", 2 interfaces, where should the packets suppose to go?), now i am able to ping from internet. I tested this: * booted foxboard with DHCP and without the cable connected, than i started the GPRS link, it worked without default gateway.
I dont have much expertise in firewalls, but i have noticed that: * i am unable to find open ports on the outside IP * i cannot connect from internet TO foxboard, but, i can connect from the foxboard TO internet Anyone with knowledge on firewall can confirm if it is possible to have this rules? Knowing that i would need to: * with DHCP enabled, delete the default gateway assigned by DHCP server if the foxboard gets an IP for the eth0 and a GPRS Link is established, and add a new default gateway with the outside IP, with a script!
