В связи с проблемой https://dnsflagday.net/ понадобилось внутреннему серверу BIND работать с пакетами EDNS.
Но данные пакеты дропает Juniper DNS ALG.
Есть два пути:
set security alg dns disable
set applications application DNSnoalg term 1 alg ignore set applications application DNSnoalg term 1 protocol udp set applications application DNSnoalg term 1 destination-port 53 set applications application DNSnoalg term 2 alg ignore set applications application DNSnoalg term 2 protocol tcp set applications application DNSnoalg term 2 destination-port 53
policy untrust-to-dmz-dns { match { source-address any; destination-address DMZ-DNS-SERVICES; application [ junos-ping DNSnoalg ]; } then { permit; } }
