Description
In 2.1x and previous versions, the GW field in pftop showed the IP:port of the NAT applied to the connection, the src as the original internal source and the destination as the original destination.
For instance, where internal host 10.0.4.4 has a HTTPS connection up to Apple @ 17.172.239.115, NATed to public IP 18.2.3.4, in 2.1x you'd get:
PR DIR SRC DEST GW tcp Out 10.0.4.4:52018 17.172.239.115:443 18.2.3.4:23961
In 2.2, that ends up being:
PR DIR SRC DEST GW tcp Out 18.2.3.4:23961 17.172.239.115:443 10.0.4.4:52018

I took a quick look at it, and looks like it is also broken on stock FreeBSD (not tested to confirm). Looks like the issue is in the following block of pftop.c, but I don't know enough pf internals to be sure about how to fix:
1126 #ifdef HAVE_PFSYNC_KEY
1127 if (s->direction == PF_OUT) {
1128 print_fld_host2(FLD_SRC, &s->key[PF_SK_WIRE],
1129 &s->key[PF_SK_STACK], 1, s->af);
1130 print_fld_host2(FLD_DEST, &s->key[PF_SK_WIRE],
1131 &s->key[PF_SK_STACK], 0, s->af);
1132 } else {
1133 print_fld_host2(FLD_SRC, &s->key[PF_SK_STACK],
1134 &s->key[PF_SK_WIRE], 0, s->af);
1135 print_fld_host2(FLD_DEST, &s->key[PF_SK_STACK],
1136 &s->key[PF_SK_WIRE], 1, s->af);
1137 }
1138 #else

This is not a bug or problem.
Interal structures in pf make this be displayed this way.
