I will try fresh installation of FreeBSD 11.2-RELEASE
And see how it works.
Maybe something was corrupted during upgrade.
Just FYI please look on my pf.conf and squid.conf:
*# cat /etc/pf.conf*
outif=re0 #outer interface
inif=re1 #iner interface
outip="(" $outif ")" #outer ip
inip="(" $inif ")" #iner ip
innw=$inif:network #iner network
inbc=$inif:broadcast #iner broadcast
bc="255.255.255.255" #anycast
set skip on lo0
set block-policy drop
scrub in all
nat on $outif from $innw to any -> $outip
rdr on $inif proto {tcp,udp} from $innw to any port 123 -> $inip port 123
block log all
pass from $innw to $innw
# this is my machine client ip
# i have allowed full access form my PC
pass from 192.168.0.104 to any
# this 2 lines passes any traffic from gateway itself
pass from $outip to any
pass from $inip to any
# i don't know why but option "set skip on lo0" doesn't work
# so i additionally pass the whole traffic thru loopback interface
pass on lo0 from any to any
