in most firewalls like smoothwall,monowall and pfsense you can find Squid cache, is this in ZeroShell?
i didn’t deploy zeroshell, but i want to intall it, (Squid cache) feature is very important for me.
Zeroshell is mainly a router. Adding proxy functionality takes resources and possible instability. I’d suggest installing squid on a different server, instead of using the built in, which doesn’t support caching.
