Hello,
I have a problem with a Teltonika RUT200 and NAT Rules. I want to nat from a network named lan_BACK to a defined ip.
In a router with an older firmware (RUT2M_R_00.07.06.3) everything works fine. In the new firmware (RUT2M_R_00.07.09.1) we observe that the devices in the lan_BACK network go out with IPs in the lan_BACK instead of the IP defined in the NAT rule.
The difference is that in the older version we could setup the destination zone in the NAT rule, while now it’s no longer possible. The option to select the destination zone doesn’t exist at all now and it’s set to Device instead of wan.
I think this is messing up with the router’s firewall rules based on zones and thus it’s not working. It’s a known problem? I’m using a wrong approach? I already updated the modem to the latest.
Thank you for your support.
