Sure, no problems. I am sure that my pf rules are ok, because I use
them in several FreeBSD 10.x installs.

Testing with a simple rule set like this:

scrub log on $ExtIf all reassemble tcp fragment reassemble
nat on $ExtIf from $IntIf:network to any -> ($ExtIf)
pass all


ICMP proto works without problems. But UDP and TCP connections, fails.
I can see how traffic flows in this FreeBSD vm acting as a firewall
(using tcpdump), but connections aren't returned.

I have tried to disable tso, tx and rx checksum, etc without luck.

This FreeBSD vm is created as Gen1 hyper-v guest. I don't know if it
can Works as Gen2. But configuring another vm inside this Hyper-V
using Debian, iptables works without problems for all protocols.

Any idea?
