Hi all,
I have had our DNS server published through ISA for some time.
All seems to work fine, however, I keep getting the following alerts
reported
DNS Zone Transfer from Privileged Ports detected from 158.43.xx.xx:48449
to 62.189.xx.xx:53
where the second IP is our DNS server.
I checked from the internet, and I can do a zone transfer using nslookup
on our dns server, so the request seems to get server.
Can anyone let me know if this is a problem. Why does the DNS filter
check for transfers from high ports ?
