Network Address Translation A Network Address Translation (NAT) lets home office or small network environments use internal IP addresses for the devices within the network, while using one external IP address to communicate with the outside world (Wide Area Network). However, many Small Office Home Office (SOHO) routers provide NAT services that are not fully H.323 compliant. Therefore, this solution is provided to enable the user make calls outside the internal network.
PAGE 206
Appendix A Network Address Translation 4. Enter the NAT’s external IP address into the NAT outside (WAN) address field. Write down the Fixed TCP and UDP port numbers displayed on this screen. These numbers typically are the following default numbers: TCP: 3230 to 3231 UDP: 3230 to 3235 5. In your NAT, reset the fixed ports from step 4 to be permanently open, and redirect them to the IP address of your ViewStation. 6.
