DNAT to Different Subnet

Hi All

I've run into a bit of a brick wall with this one.

I'm using Sophos UTM9 as a virtual appliance in vmware.

I have a /28 block of public IP addresses and currently use UTM 9 to Firewall our network and DNAT our internet facing services.

All was working fine until I moved a couple of our web servers to a different subnet in our private IP range. There are no connection problems between the UTM9 and the problematic hosts. When I attempt a connection to the HTTPS port 443 it logs the correct NAT rule but the browser doesn't connect. I've also used nmap from a remote server and reports that 443 is not accessible.

Has anybody got any ideas?

Thanks in advance
