Using 2 SIM Injectors with one Router

Hi,
I want to use two SIM Injecors with one Router. The two devices are not on the same network. The routers are always at a different location.
I activated the FusionSIM agent with port 50000 on the router. My firewall at the office forwards this port to the SIM Injector’s local IP. Now if I want to use a second SIM Injector I can give it port 50001 (and a other IP) and forward that port in my firewall, but I can only inject one port in the Fusion SIM agent (support.cgi).
Is there another possibility?

That would be nice
Maybe @TK_Liew has an idea?

@mldowling, you’re using the SIM Injector very intensively, do you have any experience with it?

Thanks
Dennis
