Hi,

Can anyone help me in configuring unbound to listen for client queries
on multiple ports and answer to clients.
interface: <ip address[@port]> can be used to hardcode the port but is
there any way that i can define a range of ports for unbound server
to listen client queries let say range from port 1024-54444.

Hello,

Can anyone help me in configuring unbound to listen for client queries
on multiple ports and answer to clients.

I don't think you can listen on a range of ports, you need to list them
individually.

interface: <ip address[@port]> can be used to hardcode the port but is
there any way that i can define a range of ports for unbound server
to listen client queries let say range from port 1024-54444.

I'm wondering why you'd do this? If you really need this, I'd do it with
DNAT/REDIRECT instead of creating ~50k sockets.

Cheers,
Simon

Are you possibly looking for the options outgoing-port-permit and outgoing-port-avoid, which tell unbound to use or avoid specific port ranges for its own outgoing queries to authoritative DNS servers?
