Fix routes to tunnel interface

Hi,

on my TRB140 with OpenVpn connection all works fine. After reboot the tunnel will be come back and internal LAN will give also access.

But unfortunately after each reboot or tunnel break the routes to the tunnel are lost. Also the ip6 address on the bridge interface have to type in again.

Have done all configs in /etc/config/network, but without success.
Is there any hint possible to arrange a fix implement of routes and ip addresses.

  • Firmware version

TRB1_R_00.07.13.1

  • Kernel version

5.4.289

  • Local device time

2025-04-12 11:54:31

Maybe also the network config is helpfull.

Here the bridge interface, where fix ip6 address should be set:
config device ‘br_lan’
option name ‘br-lan’
option type ‘bridge’
list ports ‘eth0’
list ports ‘rndis0’
option stp ‘0’
option mtu ‘1500’
option ip6addr ‘20a02:a00:e000:7e::2/64’

And here the route for the tun_c_1 interface:

onfig route6 ‘6’
option table ‘254’
option mtu ‘1500’
option interface ‘tun_c_1’
option target ‘2a02:a00:e000:7e::1/64’
option gateway ‘2a02:a00:e00f:ffff::1’
option metric ‘1’

Thanks for a hint.

Markus

Maybe a update for clarification.

The issue mostly exsist, if I stop and start via SMS Utilities the mobile connection. The tunnel interface tun_c_1 will be every time set up again.
But the relation to the default route is lost and new set / don´t exsit correctly.

And here I stuck as mentioned above reg fixing the route over a stop/start action on mobile interface.
