Description

Maintainer: @nmav
Environment: aarch64, Xiaomi Redmi Router AX6S(mediatek/mt7622), OpenWrt 23.05.0 r23497-6637af95aa

Description:
I using my router as client for remote Openconnect server. It worked perfect with OpenWrt 22.03.5 but stopped after upgrade firmware to 23.05.0. My investigation bring me two issues:

  1. no specific route to the ocserv's IP-address after connection is up
  2. wrong MTU on the openconnect interface (always 1500 whatever set in the config)

I managed to working connection by manual add the route and change MTU to 1436 but I don't know why it's not working automatically.
