I ma trying to setup a IPSEC site to site VPN between MS Forefront TMG 2010 to a Cisco SRP527W router
I am running the latest firmware on the router
I cannot get the 2 to connect, I have matched as best as possible the settings on the SRP527W as are in Forefront
I can't see any logs to indicate why this is not working
If anyone has any ideas?
