VPN through Microsoft Proxy Server 2.0

I want to VPN to my company's internal network from home. At the company end is a VPN 3000 Concentrator.

However, at home my PC connects to the Internet through another machine running Microsoft's Proxy Server; using Winsock Proxy for normal TCP connections. Is there a conflict between Winsock Proxy and the VPN client?

Any thoughts much appreciated,

Matt

Re: VPN through Microsoft Proxy Server 2.0

It would not work with proxy based firewalls, even using the IPSec thru tcp feature, see:

It would work if the server is only doing NAT (with the IPSec thru UDP or IPSec thru TCP options) but not

with proxy.
