Connecting the Network
Figure 9: Example Network Diagram of a Firewall or Proxy Confi guration
Proxy and Firewall Compatibility
Proxy and Firewall confi gurations
may become necessary
when the IP-Link is connected to a LAN/WAN that is protected by
a commercially available Firewall, Proxy, or NAT enabled router.
Examples of these would include Cisco, NetGear, LinkSys, or
WatchGuard Technologies. Also, some ISPs provide IP Address
ranges that are already fi re-walled at the NOC or ISP Head-End.
Make sure that your IT Department or ISP can create a mapped
TCP port 39288 on your fi rewall/proxy to TCP port 39288 on
the assigned IP Address of the IP-Link.
Only with proper confi guration of the Firewall/Proxy are con-
nections to the IP-Link from outside of the local area network
going to be possible. Check that the Firewall/Proxy port is not
set to time out or reset after a specifi ed amount of time passes
unless there is no traffi c from the remote PC.
