New user here.

I created a rule:

Source: Interface: WAN (interface connected to internet)
Destination: Interface: VMNet (IF of virtual machine)
Service: Port 1933 TCP
NAT: Destination Map: VMSystem (host running on VMware)

I tried various options, also using Source ANY and destination ANY, with and without NAT-Destination Map. Also using a specific Host as destination (VMSystem).

I press APPLY after implementing a rule. The rule is quite on top with nothing blocking traffic off beforehand.

Problem: I cannot see Kerio Winroute creating a TCP listen socket on my firewall host. There is simply nothing listening on port 1933.

My OS is Windows 2003 Server R2 SP2 with all updates. Windows Firewall is disabled, Application layer gateway is disabled also.

Is there something I am unaware of or should be doing? The firewall is great, but I would need to map ports to internal systems.

Port mapping does not bind any socket to listen state. The firewall is inspecting all packets and no listening socket is necessary.
