Greetings, ISA 2000 - Standard Ed. - Stand Alone Windows 2000 DSL internet connection (non PPOE - MAC authentication) Internal ISA Card plugged into switch Clients plugged into switch Clients are SecureNat with ISA All clients can browse the internet I'm trying to establish a PPTP tunnel with My ISA server in my home office. During testing I was able to establish the tunnel fine. I sent the server To the remote office and the tunnel won't connect - reason, unreachable. I can't ping the IP of the remote ISA either, although - as stated above - Clients behind it can browse the internet. From the remote ISA I can't browse The internet or even ping something simple like www.yahoo.com From a computer sitting anywhere on the internet, when I ping the public IP address of the remote ISA with the -A option it tries to resolve to a dns record given by the DSL provider but requests time out. Now, Because I don't have the ISA Server named what is set in the DSL's DNS servers I'm thinking that this is the reason why I can't establish my tunnel or do anything from that server itself. I know some ISP's - namely cable ISP's require the connecting computer to have a unique computer name - the DSL provider claims this is not the case but I can't think of anything else, am I missing anything - please tell! I know that when I change the name of the server to match what the ISP has I have to create a new account on the remote ISA for the home ISA to use for establishing the tunnel. Is there anything else that I have to do for the ISA to continue working as a firewall? Thanks, Casey
