Internal IP/Interface selection

[mitchskis]

Hello, All -

Is there a knob to fiddle that allows for the setting of the default interface to use for traffic sourced from the opnsense instance itself? I've poked around but can not seem to find one.

The problem: IPv6 traffic sourced from any of the WAN interface ips is dropped. IPv6 traffic sourced from the LAN ip is routed as expected. I do not (yet) have a root cause as to why traffic is dropped.

Thanks!
