Yeah, you can dump the ICS gateway setup and use a NAT router as the
gateway device for the LAN and WAN that cost as much as mcafee.

Then you can use IPsec behind the NAT router that's on the O/S's with
AnalogX Secpol rules for protecting the LAN and the Win Networking Ports
behind the router.

Bim, bam, boom and you can stick a fork in it, because it's done. <g>

You may want to secure the machines on the LAN a little bit.
