5.5 Special Application
Micro VoIP 200 has a natural firewall that rejects any
unsolicited
data from traveling into a
computer on the LAN network. Basically, if you didn't ask for the data, it isn't going to pass through the
firewall. A
Special Application
is one that breaks this rule. For some applications, you can configure the
Micro VoIP 200 to allow them to pass inside Micro VoIP 200 to a specific Notebook/PC by setting this
“Special Application” list.
For a certain special application to pass through Micro VoIP 200, first, a trigger packet that has a
destination port falling in the
range between
Trigger Start Port
and
Trigger End Port
must be sent
from a Notebook/PC in the LAN side out to the WAN side. Second, the packets of the special application
from the internet must have the destination port falling in the
Incoming Port Range.
These packets then
will be forwarded to the Notebook/PC that has sent the trigger packet.
