Re: [squid-users] Problems forcing mandatory proxy use.

is there any need to use NAT. you could simply forward all data to the
squid by setting it's IP address as the DMZ server in the WAN setup
page. which would send all incomming DSL data to the IP address.

if it's a tight network your after you should think about have the squid
dual homed, one connecting to the router/firewall and the other to your
network, thus forcing all data to pass through the proxy. also the proxy
may be proxying data on more ports than 80 such as https on port 4** ect.

i have a GD834g too but havent tried the above as i use NAT and not a
proxy at home.
