DNS Zone Tranfers not working through PA

L2 Linker


I have a PA in front of a DNS server and since the date we installed the PA, the DNS zone Transfers to the remote site is not working.

The remote DNS admin stated that there are timeouts and that the firewall should allow fragmented packets to pass through.

Any idea on what could be the issue on PAN side?

Hello Vinesh,

the paloalto device allows fragmented packets.

Please verify that you have a policy that allows this traffic.

Also PLEASE verify that you do not have a zone protection profile that has "block fragmented traffic" selected.
