I am using the IP60 appliance behind another NAT device, and I am having problems with some applications.
What should I do?
By default, the IP60 appliance performs Network Address Translation (NAT). It is possible to use the IP60
appliance behind another device that performs NAT, such as a DSL router or Wireless router, but the
device will block all incoming connections from reaching your IP60 appliance.
To fix this problem, do ONE of the following. (The solutions are listed in order of preference.)
Consider whether you really need the router. The IP60 appliance can be used as a replacement for
your router, unless you need it for some additional functionality that it provides.
If possible, disable NAT in the router. Refer to the router’s documentation for instructions on
how to do this.
If the router has a ―DMZ Computer‖ or ―Exposed Host‖ option, set it to the IP60 appliance’s
external IP address.
Open the following ports in the NAT device:
UDP 9281/9282
UDP 500
UDP 2746
TCP 256
TCP 264
ESP IP protocol 50
TCP 981
I cannot receive audio or video calls through the IP60 appliance. What should I do?
To enable audio/video, you must configure an
IP Telephony (H.323)
virtual server. For instructions, see
Configuring Servers
on page 236.
I run a public Web server at home but it cannot be accessed from the Internet. What should I do?
Configure a virtual Web Server. For instructions, see
Configuring Servers
on page 236.
I cannot connect to the LAN network from the DMZ or primary WLAN network. What should I do?
By default, connections from the DMZ or primary WLAN network to the LAN network are blocked. To
allow traffic from the DMZ or primary WLAN to the LAN, configure appropriate firewall rules. For
instructions, see
Using Rules
on page 238.

I have exceeded my node limit. What does this mean? What should I do?
Your Product Key specifies a maximum number of nodes that you may connect to the IP60 appliance.
The IP60 appliance tracks the cumulative number of nodes on the internal network that have communicated
through the firewall. When the IP60 appliance encounters an IP address that exceeds the licensed node
limit, the
My Computers
page displays a warning message and marks nodes over the node limit in red.
These nodes will not be able to access the Internet through the IP60 appliance, but will be protected. The
Event Log
page also warns you that you have exceeded the node limit.
