I've been trying to setup so that an external box can ssh into a box (host1) on my internal network behind ASL 5.200. I've tried various combinations, but none work. ssh to the outside works fine.
Rule Type: DNAT/SNAT
Packets to match Source address: ??? Destination Address: host1 service ssh
Change Source to: ???? Address: ???
Change Destination to: Address Service destination ssh(22)
Help needed as I'm not sure what destination and source are referenced to.
