One of these is probably what fixed it:

Modified files:
sys/netinet ip_output.c
Log:
If `ipfw fwd' loops an mbuf back to ip_input from ip_output and the
mbuf is marked for delayed checksums, then additionally mark the
packet as having it's checksums computed. This allows us to bypass
computing/checking the checksum entirely, which isn't really needeed
as the packet has never hit the wire.

sys/netinet ip_output.c
Log:
Calculate any delayed checksums before handing an mbuf off to a
divert socket. This fixes a problem with ppp/natd.
