xDSL pppoe route not found with recent upgrades - Muti WAN

[wget]

Hi there,

I'm debugging the inability for my backup WAN2 (xDSL based) to be used. WAN1 is the default gateway for both IPv4 and IPv6.

Pinging or using curl against the src WAN2 address PPPoE address is now reporting 'no route found' (timing out with curl). The problem appeared with some dot releases from 20.7, but I haven't noticed which one.

Code: [Select]

curl -6 --interface 2a02:a03f:afe7:xxxxxxxxxxxxxxx -k -L -g '[2a00:1450:400e:80d::200e]'
I'm investigating what recent OPNsense changes could have caused this, but I have to admit I'm struggling finding the culprit as changing the default route to WAN2 is still giving the same issue (a far gateway issue?) :/

Does anyone could help me narrowing down the issue?
