Setup is ISA 2004 with VPN enabled utilizing PPTP. Remote clients are all behind a LINKSYS DSL router. 1st client connects = no problem. When 2nd client connects, the first client's connection is severed and the 2nd client works fine. Clients are NAT thru the DSL router with PPTP pass thru enabled. Is the problem w/ ISA or my DSL router? Anything to do with the fact that the clients all utilize a single public NAT address and ISA sees multiple connections coming from one IP? At a loss....
