If you don't need mode 1 MODE: I[_] !!DISABLE IT!!
If you use mode 1, make sure you limit the access to the server you want to have it access to.
This is a ; seperated list of ip addresses
In mode 1, the viewer define server + port ... if you don't limit the access someone can use your repeater
as proxy to go to other severs.
We are working on an update, so you can preset a list of the allowed outgoing ip:port pairs instead of the ip addresses only.
