Turn blacklist

[Eirikr70]

Hello,
Before setting up an ejabberd server (as a docker container), I used to operate a matrix/synapse/coturn server.
In order to secure the coturn server, there is a standard list of denied peer ip's, which seems similar to the turn blacklist in ejabberd. The standard denied peer ip's list is as follows (according to https://matrix-org.github.io/synapse/v1.56/turn-howto.html)

• 10.0.0.0-10.255.255.255
• 192.168.0.0-192.168.255.255
• 172.16.0.0-172.31.255.255

Since I am far from being a network expert, I have initially considered that a similar list should be put in place as my turn blacklist, but then the turn server didn't work properly.

Is there any standard blacklist for excluding internal IP addresses for security ?

You could check the list suggested by Enable Security. However, the list of address ranges that can safely be blocked depends on your environment. E.g., if your server is running within a local network which is supposed to be able to use TURN, that network's address range must obviously be whitelisted.
