Couple of things:
1) Where did this "virtual" IP address come from?
2) LAN means local area network. Isn't "local LAN" somewhat
redundant?
3) You have no "local LAN." Everything connected to the hub is all
one LAN with the cable LAN.

^^^^^^^^^^^
I would strongly suggest you not trust IP addresses when you are
hooked up to a untruested network like a coax cable LAN.

Do all of the link lights come on?

From what you described, your FreeBSD box should talk to the outside
just fine. However, from what you descrbed, it is not acting like a
gateway for anyone.
