VPN and TCPIP

[Kevin Cook]

I have an NT 4.0 svc pk 5 box setup with ras/vpn. I have asked many
so called 'gurus' this question - but nobody can give me a straight
answer: After a user makes their connection to their ISP, and in the
DUN they then dial the vpn server - how do they get the tcpip to go
through the vpn tunnel vice out throught their ISP?

I ask, because I need my users to do the above and be able to access
our website through a vpn. It seems no matter what I try - I cannot
get their web browser to go through the vpn. BTW, netbui works fine
through the tunnel.

Is this all smoke and mirrors - or is there really a solution?

Thanks.

Unfortunately what you seem to want is not going to work, at least not without some sorta major tinkering.
If your VPN clients are connecting up and getting valid internet ip the vpn connection will effectively hijack the ISP connection and route all traffic to the net over the vpn rather than the ISP route.
If your vpn clients are connecting up to a proxy server with vpn installed and getting an internal address (10.x.x.x , 192.168.x.x etc) then what you are asking is doable because to get to the website the traffic will not be routed via the vpn.
I am sure you could mess around with adding static routes for specific ip's but that's a bit unplesant. Got more details?
