Oops, sorry. That was an error while cutting and pasting. Those lines are
only present once in the actual file.

> run 'ipsec verify'

On the gateway sever, ipsec verify shows everything [OK] (except for the TXT
stuff in the DNS section).

On the client computer, ipsec verify shows everything [OK] except:
Two or more interfaces found, checking IP forwarding [FAILED]

However, the client computer only has one network interface (eth0).

Yes, it was enabled.

No, I hadn't done that. Thanks for the suggestion! After doing that, I can
ping the gateway computer. However, I still can't ping any of the computers
behind it.

I have 50 and 500 opened up, but I don't remember seeing any mention of port
4500. I've tried turning the whole firewall off, and that doesn't seem to

It seems like I'm almost there...I just need to be able to access the
computers behind the gateway!

Here the updated information files for my current configuration (no
debugging info now, promise):
http://leafnode.net/ipsec/ipsec.conf (identical between computers) 

Thanks for your help!
