On this page you can control which IP addresses are allowed to access
your Jabber server. If any addresses are entered into the Allowed client
IPs section, then only those addresses will be granted access - otherwise
any address will be allowed to connect. However, any address listed in
the Denied client IPs section will be blocked, whether it is on
the allowed list or not.
Both fields accept IP addresses (like 1.2.3.4) or IP/netmask pairs
(like 1.2.3.0/255.255.255.0) for specifying an entire network.
