Am I right in assuming that the FreeBSD machine is also running on =
Amazon?

There=E2=80=99s a know problem with pf and TSO which manifests (among =
other places) in EC2 instances.
It=E2=80=99s actually been fixed in stable/10, so the 10.3 release will =
have the fix.
In 10.2 you can work around the problem by disabling TSO (ifconfig foo0 =
-tso should do the trick).

See PR 154428, 193579, 198868 for more information.
