11.6 NAT

Frequently Asked Questions

Ans: The router can only block messengers based on Domain names, URL Keywords, IP Addresses or Port numbers used for communication. Blocking of messengers (like skype) which cannot be identified by any of these methods is not supported by the router.

Q18. How do I make my web server accessible from the internet?

Ans: The following steps will guide you through this setup:

Connect your Web Servers to the DMZ Port and configure DMZ Systems in a specific private subnet (e.g 192.178.1.0/24).

Go to NAT → Virtual Server/NAPT and add an entry to redirect your Server traffic (eg. HTTP, FTP) from the Global IP to the DMZ Internal Server IP Address.

Instead of Virtual Server configuration, you can also use One-To-One NAT. Go to NAT → NAT Configuration, and configure a One-To-One NAT entry mapping the global IP Address to the Internal Server IP Address.

If Firewall is enabled, go to Firewall → Policy and click on In. Add Port Filter and Permitted IP Rules to allow the Server traffic from WAN to LAN.

Q19. I am unable to access my server in the DMZ Port. What could be the problem?

Ans: To troubleshoot this issue, follow the below steps:

Ensure that Virtual Server or One-To-One NAT has been configured to access the DMZ Server. Specifically verify the global IP Address, private IP Address and Port Number configuration.

If Firewall is enabled, ensure that inbound firewall policy rules have been added to allow the DMZ traffic. In the IP Permitted Rule Page, if specific IP Address has been configured, ensure that Private IP Address and not Public IP Address has been configured to allow access.

If everything is proper but still not working, then verify Status → Log Tables → Blocking Log to see the reason why the traffic has been blocked from entering inside.

Q20. I am using SIP-ALG for VoIP Calls between my branch offices. But I am not able to register my phones to the SIP Server. What could be the problem?

Ans: Follow the steps below to troubleshoot this issue:

Verify the phone network configurations for default gateway and dns server

Verify the phone sip configurations for user name, password and proper registration port

If firewall is enabled, ensure that the SIP signaling port is not blocked.

Ensure that the SIP Server IP Address is reachable by pinging to it.
