I am trying to get nebula working on tun1 with pf as my firewall. If I
turn pf off, everything works. How to I tell pf to ignore / let
everything pass on the tun1 device.
freebsd-version = 13.0-RELEASE-p5
The following is my pf.conf.
vtnet0 = "vtnet0"
nebula1 = "tun1"
icmp_types = "{ echoreq unreach }"
table <bruteforce> persist
table <rfc6890> { 0.0.0.0/8 10.0.0.0/8 100.64.0.0/10 127.0.0.0/8

172.16.0.0/12 192.0.0.0/24 192.0.0.0/29 192.0.2.0/24
