Didn't work. :-( However it did change something. I now have this
mystery in the IPSec Policy summary on the ISA server. 192.168.1 is the
remote network however there is only 1 subnet on that end. The router is
serving up DHCP addresses to the client PC's on that end in the
192.168.1.100 - .200 range. Why am I seeing these subnets?

 

Remote Network 'Chicago' IP Subnets:

    Subnet: 75.49.147.185/255.255.255.255

    Subnet: 192.168.1.1/255.255.255.255

    Subnet: 192.168.1.100/255.255.255.252

    Subnet: 192.168.1.104/255.255.255.248

    Subnet: 192.168.1.112/255.255.255.240

    Subnet: 192.168.1.128/255.255.255.128

 

Local Network 'Internal' IP Subnets:

    Subnet: 192.168.26.0/255.255.255.0

That might do it. The person I got the link from had issues that sounded
very similar to yours.

        This could be the solution to the problem I'm having with the
linksys router. It gets connected, get to quickmode and then drops.
