Special Applications

Special Application

If you use Internet applications which have non-standard connections or port numbers, you may ﬁnd that they do not function correctly because they are blocked by the XC-DPG603 ﬁrewall. In this case, you can deﬁne the application as a “Special Application” in order to make it work.

Note that the terms “Incoming” and “Outgoing” on this screen refer to trafﬁc from the client (PC) viewpoint.

Using a Special Application on your PC

Once the Special Applications screen is conﬁgured correctly, you can use the application on your PC normally. Remember that only one (1) PC can use each Special application at any time.

Also, when 1 PC is ﬁnished using a particular Special Application, there may need to be a “Time-out” period before another PC can use the same Special Application. If an application still cannot function correctly, try using the “DMZ” feature, if possible.
