Question

We use the Teltnika RUT240's as an L2TP client which pulls a public IP. This is then used to nat out to the internet and for inbound traffic.

This has worked fine on the older firmware but when I've upgraded a Teltonika to firmware RUT2_R_00.07.01.4 the port forwards no longer seem to work?

I've made sure the port forward has the correct zones and added the firewall rules so it's allowed if coming in over L2TP but a TCPDump doesn't show it ever forwarding to the internal device. On the old firmware it does?

Thanks

Ignore. It looks like tcpdump is changing the source ip to a hostname of the teltonika so it wasn't matching when doing tests. it is working fine :)
