after succesfully setting up my isa server 2004 it works fine for the internal clients accessing the internet. but the moment i set up VPN connection (to allow external users to tunnel in) the internal clients will not be able to access the internet anymore. (something goes wrong with the internal to external routing).
i'm sure i did set up vpn connection fine in the isa server 'cos i went to the vpn property and to the best of my knowledge i did set things up fine.
what could be the solution here please?
the idea is to successfully set up vpn tunneling from the external to internal network while the existing internal clients will remain accessing the internet with no problem
