is your system configured with the GATEWAY option?
what value does the sysctl variable "net.inet.ip.forwarding" have?

IP packet forwarding is required to be disabled by default by some
RFC (the number of which currently escapes me 8-).

to enable it, configure your kernel with "options GATEWAY"
or put the line:
	sysctl -w net.inet.ip.forwarding=1
in your rc.local.

the latter solution will enable packet forwarding.  the former will
enable packet forwarding, _and_ give you more mbuf space.  I'd say
that, if it's practical, do the former, but to test and make sure that
these solutions work for you, do the latter.
