Really dumb question, but is IP Masquerading turned on by default?

!!! WARNING !!!  Danger Will Robinson!

It looks like you're running IPSec *AND* loading the ip_masq_ipsec kernel
module.  I don't even know how this is possible, but it's definately
*WRONG*.  You need to make sure you're using a kernel with KLIPS (IPSec in
the kernel name on my website).  The default CD-ROM kernel contains IPSec,
but the default floppy kernel doesn't.  Do *NOT* load the ipsec masquerading
module...KLIPS (firewall=VPN Gateway) and ipsec masquerading (ipsec client
on an internal system) are incompatible.

Confusing, but saddly, it's the current state of affairs.  Note this also
means you cannot use the firewall as a VPN gateway while masquerading
internal IPSec clients...the funtions are mutually exclusive.

Otherwise, your config looks to be OK...
