Asuswrt-Merlin RT-AC56U 380.58_0
USB 3G modem Huawei is connected to USB port as the only WAN connection. All seems to be configured well. When I did a test run with different mobile line, I had no problem. Now, I am on site 8 hours away, and I must install this, and something is wrong with routing.
Modem connects. It signals that with a light. Router receives WAN address correctly. I recieve DNS addresses from my provider correctly. My script updates DDNS correctly (verified). VPN server is up and I can connect to OpenVPN server on a router from another device using another data line. Ergo, the Internet is perfectly accessible to the router.
But, when I connect to the router with any device, e.g. computer, I can not conncet to the Internet from that device. I repeat: same setup with a differnet line (from my mobile phone) worked perfectly. Now in the modem is dedicated Data line. But, line from the phone is different (voice + data) and was double NAT-ed by my operator (WAN address is 10....) and this dedicated data line provides actual external WAN IP address, so - no double NAT now.
Tried rebooting a router with USB modem plugged and hot swapping modem out and back in. Same thing.
Seems to me the problem is caused by a routing table.
My current IP WAN is: 37.244.181.203
System Log - Routing Table - IPv4 Routing table seems to me off:

which relates to the log:
Help is critically appreciated as I must fix this somehow VERY quicly because I am here only for a day or two. 8 hours away.
