Wan Load Balancing Multiple Regressions
Open, NormalPublicBUG
Actions

Description

There are multiple bugs with wan load balancing affecting site to site tunnels (vti/gre tunnels excepted)
multiple issues with local traffic routing, pppoe and dhcp wan interfaces
and issues with not following the pbr of loadbalancing and instead using the default route.
enable-local-traffic under the wan load balancing has no bearing on these issues

it seems that rules created in wan load balancing don't get followed by vyos itself.

vyos@E1# show load-balancing wan
 disable-source-nat
 enable-local-traffic
 flush-connections

a complete rework of the load balancing package is required it seems.
first steps should be discussed.
