I have been scratching my head on this one for weeks, I have now decided to ask the question.
We have an SBS domain with 2 hypervisors, one runs 3 File Server, one run the SBS server itself. We also have a Cisco ASA 5510 firewall.
Remote users connect into the network using the VPN client, this works great for e-mail and SOME servers. For example we have a handful of different hardware server with static addresses clients can access through the VPN no problem. But when a remote user tries to access one of these 3 FS's it cannot find the host. When I try pinging the VM's it times out, although I can ping another VM that lives on the same hardware. I have compared all NIC/Virtual Switch settings nothing wrong!
So I have then decided it may be a firewall/policy issue, so for testing I have disabled all of the Windows firewalls on the servers, I have also done a RSoP to see what GPO's are applied to the machine, and nothing out of the ordinary.
So @ this point I am stuck, so I have tried to debug ICMP packets incoming to the Cisco firewall, the pings from the remote subnet hit the firewall but dont get through it.
Any ideas, I am maybe just not seeing the wood for the trees.....Could it be I need to configured some static routes (but other servers work without this)......do I need to configure RRAS for stable routing between two subnets?
Any help would be muchly appreciated.
