Hi, I've a firewall Watchguard X500. On the log i found:
01-18 15:36:28 Deny 172.16.0.10 205.234.170.215 dns/udp 1032 53 1-Trusted
0-External ProxyDeny: DNS Invalid response (DNS-01) src_ip_nat=" x.x.x.x" src_port_nat="12133" proxy_act="DNS-Outgoing"
01-18 15:36:28 Deny 205.234.170.215 "x.x.x.x" 12133/udp 53 12133 0-External Firebox denied 165 51 (Unhandled External Packet-00)
Where "x.x.x.x" is my external ip.
I see this messages every 2-3 minutes.
172.16.0.10 is my server DNS.
205.234.170.215 is the DNS that I use.
Why it give me continuously this error and this DENY?
Thanks! Ska
