Testing with tcpdump: I see the response packages are visible on interface em0 instead on interfa= ce vlan3. It seems to me that "tunnelfib" is no longer evaluated. To verify this I added an line to /etc/pf.conf: pass in to 2XXX:XXXX:10::/64 rtable 3 no state With this workaround in place the routing is working again. Please look into this issue.
