Re: Networking problem....

Howdy,

Not too active on here but if his router is NATing a fake network to real
network that is the problem with the VPN. What kind of VPN will determine if
this will work or not. When an IP packet is masquaraded it's header is added
too, this looks like a spoofed packet to most VPN solutions and it denies
access. Hope this helps... Oh yeah, and the reason it works on dialup is
because there is no NAT taking place.
