Hi all
I am struggling in a topic that in theory would be simple or trivial.
I have Openwrt 24.02 installe on a Raspberry pi4 with VLAN segment that allocate
a) Two LAN segments, "lan" and "lan_vpn" both serving DHCP, the first on 192.168.182.0/24 the second in 192.168.180.0/24
b) Two WAN, "wan" and "wanb" both DHCP Clients, for two upstream WAN (cable and FWA)
The two LAN segments are in the same "lan" firewall zone, the WAN are in the "wan" firewall zone.
I have a VPN client running on and interface "wanu" (physical interface tun2). As you can imagine I want the traffic originated from "lan_vpn" going through "wanu".
I was using pbr for this and worked just fine, but since I am now running mwan3 I wanted to do (and I understand is recommended to do so) with mwan3 Rule.
The first attempt would be to route "lan_vpn" through the existing and working (for "lan" segment) policy, aka "wanb_wan" policy.
My clients get IP from "lan_vpn" just fine, but ping to 8.8.8.8 (to discards any DNS issue) does not work....
Of course I have checked VPN, and ping -I tun2 8.8.8.8 on the router works, so the the vpn is up, but as said I started one step before and I cannot even get the traffic going through a normal WAN.
Any hints on the problem or where start to investigate?
