MSR954 router: How can i build the NAT rules to be dynamic

[nickmc]

Hi,

i want to build the NAT rules to be dynamic(i.e. relative to the WAN interface, and not to its specific IP address).

Reason: the WAN interface(s) IP address(es) are dynamic, and may vary everytime the router is switched on (PPP I guess). Especially the LTE WAN interface.

When I create a NAT rule, I select the interface: (I have tried with both “current IPv4” and “Other IPv4”), but the result is the same and is linked to the Global IPv4 specific address, and not to the interface. 

I assume i can only setup dynamic through CLI...Can anyone guide me with the correct CLI commands to use to set this up?

Kind regards and thank you in advance,

Nick
