RRAS Dial-up and Internet access

Hello,

When connected to the internal network, our users receive a proxy server

configuration for internet browsing through our ISA/Surfcontrol server.

Works great.

When they dial-in (yes, we still have some dial-in users!), they get an IP

address and can access our servers with no problem... BUT, they can also

directly access the internet without routing through our ISA/Surfcontrol

server. How do I force their Web browser traffic through our ISA server? I

created a static route 0.0.0.0/0.0.0.0 -> ISA Server IP Address... but that

didn't work either?
