I've been setting up my Omada based network and pretty pleased so far. I have an OC200, ER7206 and a bunch of switches and AP's.

One problem I'd like to solve is with one of my WAN connections on the ER7206 which is using a Draytek Vigor 130 in PPPoE mode.

The Vigor 130 works well, PPPoE connection is established and all is good. 

But the Vigor 130 also has its own web UI where you can view status, DSL statistics, etc.  This is available on its static IP address of 192.168.2.1 and is useful to be able to access.

In order to access this I need to be able to:

1) Set an IP address on the port on the ER7206 that this WAN interface is using (for example WAN/LAN1 port -> 192.168.2.200).  This would be in addition to however the PPPoE connection is set up.

2) Set a static route on the Vigor 130 back to the ER7206 WAN port so it knows the internal address spaces of my LAN (for example "ip route add 192.168.1.0 255.255.255.0 192.168.2.200 static")

I can achieve the second point by standalone temporary connection to the Vigor 130 from a PC, but I am missing an obvious way to achieve the first point.

For reference, here's how this was possible on Unifi:

Any tips on how to achieve this?
