PPTP VPN, NAT and DHCP

nleviet007 · ‎07-09-2007

Hi,

I just bought a router 851 and have problems to create a VPN. The WAN interface get an IP address from my provider's DHCP server. I use NAT and Access List.

Do I need an additional IP address, a static one, on my WAN interface to make it work? I don't believe so but it's the answer I got.

Does anybody has a sample config file showing how to configure the router to support DHCP on the WAN, NAT access list, PPTP VPN?

Thank you,

Nam

Hi umedryk,

Thanks for your reply. I already read all these documents. I was looking for a merged document that combines these techologies. I have been told that the only way to support PPTP for remote client access and NAT on one router is to have a stastic IP address on top of the assigned DHCP that I received from my provider. The WAN interface of my router will have two ip addresses.

Any other ideas?
