3.6 Setting Firewall Parameters

With the firewall settings correctly configured, video conferences held using your TE30 are
secure.
Background
The firewall protects your IP network by separating the internal and external network
communication data.
With Network Address Translation (NAT) technology, a device on a local area network (LAN)
is allocated with a dedicated internal IP address and uses an external IP address to communicate
with external devices. If your LAN uses NAT technology, set the IP address of the NAT wide
area network (WAN) on your TE30.
Procedure
Step 1 Choose Advanced Settings > Settings > Network > Firewall. Set the firewall parameters by
