Now the biggest problem that I am having is that the Webramp uses NAT of
some sort to allow multiple IP addresses behind it to access the Internet.
This causes problems with the VPN connection. I.E. from the Webramp, I am
able to ping through the VPN and into the remote network. However, when I
attempt to ping with a host sitting behind the Webramp, I can't even ping
the PPP interface that the Webramp is assigned.
The same problem crops up when you attempt to use the VPN Pass Through
feature on the Webramp, except it is a little more succesfull. One client
behind the Webramp can establish a VPN connection to the remote PPTP
server. The second one that is brought up authenticates fine, but then
only one of them can send data. The first client is left dead in the
water.
This isn't a routing issue. The Linux PPTP server is assigning unique
addresses to the VPN connection, and multiple clients from other
NON-Webramp sites can connect without a problem. This is most definitely
something in the way the Webramp handles the NAT and VPN combination.
