You will be able to use 4 IP ranges in the next release of Zeroshell. The range exclution it is a bit more complicate and I am not sure if I can implement it in the 1.0.beta8 release.
Thats fine, the exclusions are not extremely important, I can work round them for now.
The web proxy with Clam AV antivirus could be available in the 1.0.beta9 release in January.
That would be fantastic. I don’t know how Proxy’s generally work if they do not have a locally copy of the requested file, but my requirement would be for the page to be collected from the remote site using the clients details (IP & Mac) rather than the Proxy’s. I believe this can be done using ebtables.
