Hi Tiago, They key has to be the dreaded PPPoE.

Here in the HQ, we have a PPPoA DSL modem, the public IP address is bound to it, but I configured the modem to route any incoming traffic to my ISA server. Since I'm using PPTP, there's no problem using NAT with this device.

It wasn't. I implemented Windows 2003 Server here in the HQ, where we don't have PPPoE.

See if changing the MTU fixes the problem.
