To: email@example.com Subject: Limit access to one subnet? I'm trying to figure out how to allow only 141.225.x.x to access port 8080 on a server. It's a proxy server and obviously I don't want anyone outside of campus to be able to access it.
I mean, denying access to some service is the most basic function of a packet filter. How can anybody planning to deploy netfilter not know _this_?
Anyway, in this case, it would of course be the best solution to configure the service itself to only allow on-campus access. But, alas, one needs too read the docs for the proxy software in use to make this possible, eh?
