Care to share what you trie= d with your PF.conf?

It should be something as simple as:
= rdr on <interface> proto tcp from <source host> to <physical= host> port <physical port> -> <internal host> port <i= nternal port>

Two rules = that aren't working:

# VM HTTP
rdr pass on $ext_= if inet proto tcp from any to any port { 8081, 8999 } \
=C2=A0 =C2=A0 = =C2=A0 =C2=A0 -> 172.16.0.99 port 80
# VM SSH
rdr pass on $ext_if = inet proto tcp from any to port { 2222 } \
=C2=A0 =C2=A0 =C2=A0 =C2= =A0 -> 172.16.0.99 port 22
=C2=A0
I= am able to PING the VM from the=C2=A0HOST.

From the ho= st, I am able to SSH to the VM. I am also able to do `telnet VM_IP 80` succ= essfully.

From the WAN (Internet) when I do `ssh HOST:22= 22`, I expect to land in the VM, but that does not happen.

So far I have:

# bhyve
bhyve_net= =3D"172.16.0.0/24"
=

And this NAT rule:
nat on $ext_if from $bhyve= _net to any -> ($ext_if)

Do I need another = PF rule to deal with the above issue?
