TELNET/SSH Problem

First of all, the UTStarcom WA3002-g1 is not a modem, but a router, with a NAT function. That means that you have to forward the relevant ports from the router to your server (192.168.1.39).

For general guidance on the entire process of getting up and running, consider reading the following:

• Cry Havok's community wiki guide
• DynDNS' tutorial for remote access and FTP

And, more specifically, you may want to read the following guide on PortForward.com:

• Port forwarding SSH on the UTStarcom WA3002-g1

Remember to test from outside your network. Your router may not map the ports for loopback connections (connections to the public IP originating from local devices), and consequently using the hostname and/or public IP from within your LAN may not work as expected.

By the way, I really recommend against using telnet to access your server. It is a horribly insecure protocol. FTP is not only insecure, but quite quarrelsome behind a NAT router. You can do everything you wish with SSH. Remote terminal access, as with telnet, and remote file access (SFTP) -- only a lot more secure.

To answer the follow-up question:

Many thanks for your reply. I have read all the three guides, and followed the steps mentioned in there already. As per your suggestion, I removed port 23 and port 21 for telnet and FTP. Now for port 22. I'm verifying in open port tool, it says the port is open. But whenever I try to connect via SSH

ssh host_name

...it says "connection timed out". And I'm not getting any request on my server.

Rule Application Start Port End Port Local IP Address
1    SSH         22         22       192.168.1.39

Anything else I can do??

1. Are you testing from outside your network?
2. Have you tried using your WAN IP address instead of the hostname when connecting?
3. Please try running the commands Cry Havok mentioned (and tell us about the results), if you're running a UNIX based operating system on the SSH server.

So, if you run the following commands on your SSH server, what do you get:

netstat -pant|egrep :22  
iptables -L -v -n  
egrep ssh /etc/hosts.*

I have the same problem. Port is listed as open, yet cannot connect from outside the network. Really frustrating it is.
