Guys, remotely diagnosing networking problems without having all the relevant information, like the exact IP adresses (if they are from any private range of either class A, B or C networks, they're not even routable over the internet, so don't need to be anonymized) the exact internal routers adress, netmasks and maybe routing tables will just be a wild guessing back and forth.
Also firewalls should be switched off at both client computers to rule those out.
