We have a RUT240 that we're setting up for a customer.
We need to be able to connect to it remotely via mobile data. The remote management through RMS works fine, but opening/redirecting ports does not work when on mobile, although it does work when using the WAN.
We've checked with the SIM provider and also tried two different suppliers of SIMs.
Firewall Zone doesn't specifically list mobile, so I'm assuming this is listed under WAN ?? This is set to accept with Masquerading ticked, although it makes no difference if it's not ticked.
Incidentally, the WAN IP address differs to that of the result of a whatsmyip on google.
