They are configured, because the webchat.war application can connect.
Works for me with 4.3.2 and 4.4.0. I can see IP i have entered after a server restart.
Yes you are right, but it behaves strange this field. Look when I enter the 2nd ip.
I guess it only allows input in one line like: 192.168.10.1, 192.168.10.2
Then it saves it and IPs do not disappear
