It might be.. but why is your DNS server logging your firewall's IP when your internal machines are the only ones accessing the DNS server? From: "Mike Starke" | OK, here is what I have done. I have blocked access to the nameserver | from my fw outside int. Therefore, anything coming from the outside | ip of my fw is not allowed to access the nameserver(s). Transfers | have already been restricted to just the master/slaves. | | I beleive the last guy might have been on to something: My | assistant rolled out a couple of Win2K boxes. There was a check | box that statess "Register this connections address in DNS". | | Without tailing some logs at the moment, it sounds like | this might be my culprit. Does anyone aggree?
