Router With Firewall, Using a DMZ

ViaVideo Technical Reference
If you are using a router with a firewall, and want to place the PC
running ViaVideo outside the firewall, you need to perform the
following tasks:
• Configure ViaVideo to work with your firewall's Network Address

Assign your ViaVideo to the DMZ.

Configure Your ViaVideo for NAT

In addition to assigning your PC running ViaVideo to the DMZ, you
also need to configure your ViaVideo to use your router's NAT.
To configure your ViaVideo to use your router's NAT:
1. Go to the Firewall/Lan Connection screen (System
Info>Setup>Lan&Internet>Firewall/LAN Connection).
2. Select the Using a NAT option.
3. Enter your NAT's external IP address in the External IP
Address field.
You can enter the address manually, or let ViaVideo enter it
automatically by selecting the Auto Discover IP Address
option. When you select Auto Discover IP Address, ViaVideo
automatically discovers your external IP address and enters it in
the External IP Address field.
If your network uses a proxy server, the Auto Discover IP
Address option may not work correctly. You should de-select
Auto Discover IP Address and enter your NAT's external IP
address manually in this case.
