IP Masquerading & Windows Internet Sharing

["Jon Michael Brown" <jon m brown usa net>]

I know a lot of you will laugh at this question and probably want to come
back at me with some funny remark, but be honest with me.  I am temporarily
running Windows Internet Sharing for my home network while I'm working on my
Redhat machine.  Could somebody, seriously, compare Windows Internet Sharing
and Linux IP Masquerading for me.  What kind of security do I have with
Internet Sharing?

Thanks,

Jon
