Has anyone successfully got this to work? The VPN client uses UDP encapsulation and adds an 8 byte header to the encrypted packet, which ISA then strips out. the remote gateway then rejects the connection.
I have tried the NAT-T solutions but they don't seem to work. I have set the following in the firewall policy:
UDP 500 send-receive IP-level 51 send-receive IP-level 50 send-receive UDP 4500 send-receive UDP 2746 send-receive TCP 264 outbound
I have also set some other ports but I think they are specific to this implementation. Does anyone know the exact settings that should be enabled on the client?
any advice would be appreciated.
