First, I love OpenWRT and use it quite a bit.
I'm using wman3, 2 wireguard vpns to 2 different servers, ETHs are splitted/VLAN, WAN, WAN via UMTS/USB-Dongle as backup. Most things are connected through routing.
I have the problem that after a while (maybe if UMTS goes down/up multiple times?), that static routes appearing to my 2 servers (144.76.61.xxx,144.76.187.xxx). Sometimes fix to UMTS device, but most times to eth0.2 (WAN).
If then WAN failes, the servers are not reachable via UMTS cause of fix routing entries. If I delete the rules manually, its working via UMTS/WAN again.
Please help me which module/function add such entries...
Today I added to /etc/wman3.user, not sure if it will help....:
ip route show 144.76.61.xxx proto static | wc -l -ne 0 ]; then
logger "Removed ip table 0 s2.v4u.at entry"
ip route del 144.76.61.xxx proto static
