Hi all, I have been having a few issues with my setup. My server is not only my firewall facing the internet, my VPN termination server & my Certificate Authority. I have configured the 3 VPN wizards in ISA & made sure RRAS is up a working. I can get PPTP tunnels to the VPN server, however I'm having trouble with IPSec - L2TP tunnels. Basically I'm not sure what/how the certificates play there role in my scenario, I can log into my CA through my PPTP tunnel and I can request a cert. My issue is - what cert do I request???? Must I also have a Server Cert on the server - if so, why???? I've tired & succeeded in issuing a Client Authentication Certificate & installed it in my remote machine. However when ever I try and create a IPSec VPN network connection on my remote machine I get the error "Unable to find valid certificate"???????? TIA, Andrew.
