Can anybody confirm that disabling these other options (rxcsum,
txcsum, vlanmtu, vlanhwtag, vlanhwfilter, vlanhwtso) won't cause my
adapter to lose its connectivity? This is a server in production and

Definitely. Since this is a server in production, I've obfuscated some
of the IPs, etc.
First off, here's the ifconfig. Our setup consists of a private (ix0)
and a public nic (ix1) and an ip tunnel (gif0), which is what we use

affect e.g. ICMP traffic). It seems to have been a known issue for a

Hi there,
We're running freebsd 9.0-RELEASE on a box whose primary purpose is to
act as a firewall and a gateway. Up until today, we've been using ipfw
in conjunction with natd and the divert action in ipfw to forward
packets between the freebsd box (i.e. the public Internet) and our
