One-way communication with fwip(4) between FreeBSD and MacOS X?

[Arjan van Leeuwen]

Hi,

I'm trying to establish an fwip(4) connection between my Powerbook
running MacOS X 10.4 and my FreeBSD 6.0-RC1 host. I included fwip in
my kernel and assigned an IP address to the fwip0 interface.

The weird thing is that it seems to work only one-way. I can ping my
Powerbook from the FreeBSD machine, I can even ssh to it, etc. But
from the Powerbook to the FreeBSD host, I get no replies to my pings,
and I can't access ssh.

If I do a tcpdump on the FreeBSD machine on fwip0, I can see that the
ping requests arrive, but there's no answer:

winston% sudo tcpdump -i fwip0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on fwip0, link-type APPLE_IP_OVER_IEEE1394 (Apple
IP-over-IEEE 1394), capture size 96 bytes
20:54:32.853931 IP 10.0.0.2 > 10.0.0.1: ICMP echo request, id 20738,
seq 0, length 64
20:54:33.854038 IP 10.0.0.2 > 10.0.0.1: ICMP echo request, id 20738,
seq 1, length 64
20:54:34.854122 IP 10.0.0.2 > 10.0.0.1: ICMP echo request, id 20738,
seq 2, length 64

It almost looks like there's a firewall setup to stop any incoming
traffic on the fwip interface (I have no firewall installed).

How do I proceed in debugging this?

Thanks,

Arjan
