Hi,
I'm trying to setup a backup connection using LTE modem (Huawei ME906). After many problems I make it finally to work - sortof.
I tried both ppp (and dial) directly as well as opnsense gui and modem is connecting and getting ip (internal one)

After adding static route to 8.8.8.8 I verified using traceroute that connection is working.

But when I make gateway associated with ppp0 active (or add default route manually) then 2 things happens:
- connection to internet stops working (route to ppp0 is not working)
- connection to modem gets terminated after 4 LCP echo reqests fails
New routing table:

I also tried to use this modem on clean freebsd 13.2 and I was able to set default route and it was working.
Any clue what may be wrong in my setup?
