Configuring Port Forwarding on Double NAT Networks
If for some reason the network configuration cannot be changed and your setup requires the double NAT,
you must perform the port forwarding steps twice. On the primary router, set the port forwarding to the
cascaded router's external IP address. On the cascaded router, set the port forwarding to the px6-300d's
IP address.
Bridging the Secondary Router
Make sure that the primary router (usually the one connected to or acting as the DSL/Cable modem) is the
only one with DHCP (Dynamic Host Configuration Protocol) and NAT (Network Address Translation)
enabled. The secondary should be changed to bridging mode. Ensure that the secondary router connects
to the primary router using a standard port rather than the port labeled Uplink or internet. This turns your
secondary router into a switch; however, you can still enable its Wireless Access Point if so equipped.
Refer to the documentation that came with your router for configuration information and settings.
Bridging the Primary Router
If none of the above options are available, you must enable transparent bridging on your primary router.
This may require contacting your ISP (Internet Service Provider) to configure the DSL or Cable
Modem/NAT into bridge mode, which then disables the first NAT/Firewall. After this first firewall in the
modem is disabled, the secondary router handles all the network traffic, Port Forwarding, and allows
Remote Access to work.
You should not attempt bridging without help from the ISP. If bridge mode is attempted by the
customer and not configured properly, it can render the customer's internet connection inoperable.
Primary router bridging may also require special configuration information and settings on the
secondary router.
If you configured your px6-300d using DHCP, you may not be able to reconnect to it via Remote Access
after a reboot. DHCP automatically receives an IP address from the server whenever the px6-300d
restarts. This is a very simple way to configure the px6-300d but can cause problems with your router's
port forwarding settings. The router does not dynamically update port forwarding settings and cannot port
forward to your px6-300d if its IP address changes.
To resolve this problem, try one of the following processes:
● Increase the length of the DHCP lease: Your router attempts to remember all DHCP clients and
assigns them the same IP address every time they request an IP address; however, the router
forgets clients if they do not request an IP address for a certain amount of time. Your router has a
setting for the duration of the validity of the DHCP lease. If your network requires DHCP, this
may be a good solution; however, it is not always guaranteed to work. Occasionally updating your
router's port forwarding settings may be required.
● Use Static DHCP: Some routers allow you to assign Static IP addresses through the DHCP
system based on the MAC address of the device. This ensures that the px6-300d always gets the
same IP address, and your port forwarding settings are always correct. Static DHCP allows you
to leave your px6-300d in DHCP mode. Refer to your router's documentation for more information
on configuring DHCP settings.
● Use a Manual IP Address: Changing the Manual IP address reduces the reliance of your px6-300d
on the DHCP server; however, you must perform additional configuration for it to work properly.
1. Log in to your router and write down the DHCP range it is using.
