Hi there,

I think there are some syntax errors in /etc/rc.firewall, a missing "s" for
icmptype. 

For ipv6: icmp6type instead of icmp6types  
For ipv4: icmptype instead of icmptypes

~ $ grep -n -E -w "icmp6type|icmptype" /etc/rc.firewall
462:    ${fwcmd} add pass icmp from any to any icmptype 8
464:            ${fwcmd} add pass ipv6-icmp from any to any icmp6type 128,129
468:    ${fwcmd} add pass icmp from any to any icmptype 3,4,11
470:            ${fwcmd} add pass ipv6-icmp from any to any icmp6type 3

~ $ freebsd-version -kru ; uname -rms
13.4-RELEASE-p3
13.4-RELEASE-p3
13.4-RELEASE-p3
FreeBSD 13.4-RELEASE-p3 amd64

Tested on 13.4 and 14.2.

Thank you.
