How to Block Top Level Domain with Sonicwall
Posted on 2015-02-03
What Network Objects and/or Firewall Rules could I use (or would I have to create) to block an entire top level domain with my Sonicwall? We have no need to communicate with anyone not on a .com, .net, or .org domain and the spammers have been finding ingenious ways to bug the hell out of me from their .us, .in, .info, .biz, etc. domains. I'd like to block all of these newer top level domains in a relatively easy fashion. It's extreme yes, but I'm up against the clock. Thanks in advance!
