[Astlinux-users] Adding a Wireguard null route with higher metric

[Michael K. <mic...@ip...>]

I use Wireguard VPN’s extensively and our softswitch has many peers connected to it.
One issue that is very annoying is that if a VPN route drops out of the routing table, rather than just Unreachable, Asterisk complains as below:
[May 14 07:20:37] WARNING[2082]: chan_sip.c:3781 __sip_xmit: sip_xmit of 0x2b61f424e7a0 (len 509) to 172.29.1.252:5060 returned -1: Destination address required
[May 14 07:20:38] WARNING[2082]: chan_sip.c:3781 __sip_xmit: sip_xmit of 0x2b61f458c940 (len 507) to 172.29.1.13:5060 returned -1: Destination address required
You also get the same when you try to ping it.

Can you think of any way to resolve this. I tried a null route and that didn't work.
