[Freeswitch-users] ACL for ESL issue ?

[Steven Ayre]

You need to use one or more apply-inbound-acl to allow access via ACLs you
have created.

If you don't supply apply-inbound-acl then the default will be
loopback.auto, to lock access down to local access only.

In 1.2 the default was to not apply any ACL (allow anyone), in 1.4 it
requires you to be explicit or it'll only allow local connections even if
you listen on 0.0.0.0 or ::. This is more secure.

If you're opening it up to remote access you want to be very careful about
who you allow to connect. The protocol is unencrypted, the password is sent
in plaintext, and it provides the ability to crash freeswitch or execute
system commands as the freeswitch user. So it's a security hole that you
don't want to be any more open than it absolutely has to be.
