Hi Guys

I found out after making a replica storage server, that I cannot use the DHCP option anymore. It therefor would be the best way for me to add a new subnet I think.

I have just created a new subnet quickly as a test, and it works fine, and I can access the VPN, and it gives me an address. But I cannot come in contact with servers, or even ping them, I beleive it is because it is on a diferrent subnet.

What do I have to do, to make this subnet able to contact the production subnet?
Make a new network route on the ISA, or ?

It is actually the exact problem as described here, although I cannot find the correct solution.

The default route is there, which I actually at first thaughted caused the problem.
VPN Clients to Internal Network - Route - Quarantined... Vpn Client - Internal

I can ping the VPN client fine from the ISA, but not from the client to the ISA.

Could it be that I am missing some routes in the routing table locally on the ISA ?

Do the internal servers have ISA as the default gatway?

If not, they you will need to tell them how to send replies back through ISA; this will likely mean adding routing somewhere which details your remote VPN subnet and the need use ISA as the gateway for this network.

Cheers

Thanx for replying Jason.

You could be right with this one, since the servers are configured with an another firewall at this time.
Be something is woundering me then, why I cannot ping any of the interfaces on the firewall?

Default ISA policy will block ping and your VPN subnet is probably not included in your "Remote Management Computers" group.

Cheers
