My current use of RU950 is to be a Cellular access router.
It connects to an APN an gets internet access.
Then it connects by L2TP to our Bras and receives a public ip.
Default route is via the L2TP.
The LAN devices are connected via RJ45 ports.
I do port forwarding from L2TP to LAN, and NAT from LAN to L2TP.
So far so good.
I'd like to add a RJ45 connection through the WAN port.
I'd like to do a policy based route, if possible, from a specific host on LAN to the public WAN ip and NAT it inside to outside.
The rest of the older functionality should remain unchanged.
I am having a difficulty with this setup.
First of all, I'm unsure how to do a policy based route.
Secondly, the default route from L2TP should not be disturbed.
Thirdly, the wired wan port is blocked up until I mark it as my backup port.
I did that, port went up, I lots L2TP access..cancelled it, access was not restored.
In the end I resolved it by doing a factory reset and reconfiguring it.
In case policy based route is not possible, perhaps it can be replaced by a static route to the wired WAN IP (I may know the destination ip).
