Internal Subnet to Use Different External IP address to Default
In a typical Firewall setup all internal IP address use the dynamic nat, and all internal address are presented with the default IP address of the external interface of the firewall.
However I want to have a single subnet not use the default Dynamic nat, and present itself as the next external address in our external range.
I have looked at 1-to-1 nat, but this seems more for a singe device like an exchange server, or if I specify a range it has to match on the external interface.
Any advice, I know it must be possible...
Thanks in advance..
