Heres the situation: As always, i like to test various network configurations.. My mate asked me from work to try and get this going. I'm trying to have a VPN to VPN configuration. ISA at both ends of the connection.. I can see this at nt bieng a problem with Parallels. these are on two subnets... (I noticed u can't change subnet, if I could, I spose that could change ip class..) eg 1 pc.... 192.168.x.x 2 pc.... 10.0.xx and these two have VPN, through ISA firewall... There must be no hardware (ie router) in between. I would want to accomplish all this under PD4.0.
