Microsoft VPN Client through 857 ADSL Router

Hi

I have set up a cisco 857 adsl router using CP Express (web interface) with standard NAT and firewall settings.

router seems to work fine apart from outbound pptp connections.

I am unable to use the MS VPN client to connect to our PPTP server in a remote location. I am not trying to use the VPN facilities on the 857 router, just allow pass-through from my laptop behind the router to an external vpn server.

The client instantly goes to "Verifying Userbane and Password" then hangs on this for a minute or two before failing.

Any suggestions would be apprecated.

Thanks

Gordon

Thanks DP

The second link got me going in the right direction. It was the return GRE traffic that was being blocked.

I have never had to configure a firewall in the past where you have to manually allow return traffic for outbound rules!

Cheers

Gordon
