VyOS forward rfc2136 requests

General questions

I am on VyOS 1.4
It seems its not possible to forward RFC2136 DNS update requests?

From syslog:
Oct 17 12:18:18 vyos01 pdns-recursor[673532]: msg="Ignoring unsupported opcode server socket" subsystem="in" level="0" prio="Error" tid="1" ts="1729167498.991" opcode="Update" proto="udp" remote="10.6.10.89:55400"

Use case:

  • dns-clients uses vyos as DNS server
  • vyos forwards to our internal windows-dns as upstream
  • this windows server owns our internal authorative zones
  • clients sends nsupdate to vyos for internal zones

RFC2136, opcode 5: Domain Name System (DNS) Parameters

My config:

vyos@vyos# show service dns 
 forwarding {
     allow-from 10.0.0.0/8
     listen-address 10.6.100.12
     system
 }
... 
show system name-server 
 name-server 10.6.10.10
