Subject: listen on specific IP only
Date: Wed, 20 Jun 2018 19:18:48 +0200 [thread overview]
Message-ID: <8d3124af-de51-3253-8b89-02233566c4f9@rfa.cz> (raw)
Helo,
is there a way to listen on specific IP/interface? i need it to use same
port for multiple applications - 53 for DNS and wireguard because of
firewall rules i can't controll. I have multiple IPs on the server each
for specific use. DNS recursor is listening only on private interfaces
and i want wireguard will be on public IP.
if i try
ListenPort=53
it fails with:

already in use
but all my public IPs are not used with this port:
netstat -tulpn |grep 53
tcp 0 0 172.16.16.6:53 0.0.0.0:*
LISTEN 3372/pdns_recursor
tcp 0 0 192.168.11.1:53 0.0.0.0:*
LISTEN 3372/pdns_recursor
tcp 0 0 127.0.0.1:53 0.0.0.0:*
LISTEN 3372/pdns_recursor
udp 0 0 172.16.16.6:53 0.0.0.0:*
3372/pdns_recursor
udp 30720 0 192.168.11.1:53 0.0.0.0:*
3372/pdns_recursor
udp 0 0 127.0.0.1:53 0.0.0.0:*
3372/pdns_recursor
is there any workaround for that for now? will some type of DNAT works?
Thanks Tomas
