Looks like your default gateway is wrong...  breezing through your tcpdump,
it looks like your default gateway is 24.6.61.1, not 205.159.77.234.  Change
the default gateway in /etc/rc.conf and see if that doesn't clear it up.

Subject: New computer won't talk to cablemodem


	I am in the process of setting up a "new" computer to use as a gatewy
	to the world for my home network.

	I am presently accessing the world through an @home cablemodem via a
	FreeBSD 2.2.8 machine, and natd. Works great.

	I have scrounged up an old 486 to take this machines place. I built
	3.3-STABLE on it, and started trying to make a similar setup work.
	Unfortunately I can't seem to get as far as pinging the cabemodem
	providers gateway machine :-( I must be doing something dumbe here.
	Here is what I see:

	As you can see the new machine is asking for an arp of the gateway, and
	it apperars to be making it into the arp table. Still ping doesn;t
	work.

	Simply removing the cable from the "new" machine and puting it back in
	the old one causes pings from it to start working.

	I am at a loss here. Has anyone got any troubleshooting advice for me?

	Thanks.
