you'll have to make the correct /IRCNET ADD and /SERVER ADD commands to
make it work properly.
+The special network name "?" allows the client to select the network
+dynamically on connect:
+
+ /SET irssiproxy_ports ?=2777
+
+Now the client can send <network>:<password> as the server password, e.g.
+
+ /CONNECT ... 2777 efnet:secret
+
+to connect to efnet. If there is no irssiproxy_password set, you can
+omit the ":" and just send the network name as the password.

By default, the proxy binds to all available interfaces. To make it
only listen on (for example) the loopback address:
