I've set up a web proxy on my LAN and I thought I'd just go in and block all outgoing access to port 80 except from the machine running the proxy. But it's not obvious to me how I can do that with the 4100 access controls.
The router seems to want me to explicitly list the machines I want to block, instead of blocking all by default and listing the one exception. Is that true or am I missing something?
Thanks,
G.
