I have a TZ180 with enhanced OS. It has an SBS 2003 Server behind it and everything works great.
I have an IPAd that I use both internally on the network and externally while travelling. The Ipad is using the URL remote.domain.com to access the exchange server remotely with no issues. When I am internal to the network on the WIreless LAN with the same IP subnet as the server, 192.168.10.x, the URL does not work when inside the network. I have created a NAT rule below:
Source trans Destination Server LAN IP Services
LANSubnets Original "WAN Primary IP" ServerPrivate ServerServices Original Any Any
I am able to Ping the URL and it comes back with the My SBS server responding so that NAT rule works. I have tried to create another rule for the server, but can't figure out the correct rule to do this. I have not modified any Firewall Access Rules and I have not created any routes.
The DNS server that controls the URL remote.domain.com is on the internet, so the SBS server doesn't do DNS for the external domain name.
Can someone give me detailed settings that I should put in the firewall.
