Use the WAN port of my TPLink to setup a separate network

Hello

I have a TL-WR940N router, on which I have installed OpenWRT.

This router is used as a wireless client to my main network so that I can plug it anywhere and it gets internet from WWAN.

I configured the 4-port switch as a lan on 192.168.0.1/24 and it is masqueraded to internet via the Firewall.
This works fine.

Now, I'd like to test a device that has a specific network configuration (static IP, specific domain, specific DNS etc.) I wanted to use the WAN port that I have on my router for that, but I cannot figure out how to make that port do the same masquerading for its clients so that they can reach the internet.

See my configuration:

So the WAN port has a static IP address 10.16.15.129, and no DHCP.

I tried to create a new FW zone (lan2) in which includes the WAN port, and add the same kind of rules (masquerading etc.) that I did for lan, but it doesn't seem to be working.

From the device (it has IP 10.16.15.167), I can ping the router on 10.16.15.129 but nothing else. I cannot even reach the ssh port to connect to openwrt, even though my ssh listens on all interfaces.

Ideally, I'd like both lan and lan2 to be able to discuss between themselves, and both should be able to reach internet through the wlan.

Any idea on how to do that? Is the "wan" port limited in some way? I cannot see it in the "switch" view, which tells me it might be a specific interface on which standard rules might not apply.

All right.. this is just simple. I fumbled a bit too much with the parameters, and it was simple.

  • I disabled wlan6, and removed it from the wlan FW zone
  • I copied the configuration for the lan2 zone from what I did on the lan zone:

And it works fine.

And here is my "interfaces" view:

I made sure to disable WAN6, which I suspect was one of the reasons the setup didn't work.
