Thread: Port forwarding / ACL / Routing

Hey Guys,

I need some help in advanced configuration.

My Setup.

UTSTARCOM 3002-g1 -------> A 5 port switch ------> One PC with 2 ethernet ports.

In MY PC (XP SP2) I have installed an emulator software for a server. Which will accept either telnet or SSH connections only. And one of the ethernet card is dedicated to this server alone. Everything works fine inside the my network. I can telnet,SSH using the local IP i.e 192.168.1.39.

Now my requirement is, I want to connect to this server from outside my network, either from office or from my friends place.

I registered with dyndns.org and got a host name. I have port forwarded the ports 23-telnet, 22 SSH to that particular IP (192.168.1.39). I verified everything on the website (dyndns.org) that the ports are forwarded and everything seems to be fine.

PROBLEM:

When i telnet from outside network

telnet xxx.xxx.xxx.xxx (my WAN IP) or
telnet my host name

I get the password prompt directly for the modem's configuration console.

I don't want this to happen. I don need the modems login. When ever i send a telenet request to my WAN IP address it should forward that request to the ip address 192.168.1.39.

I know im missing something. Can any one help?? Please let me know if you need more input or if im not clear.

login to your modem http://192.168.1.1 and make sure that Remote Administration is DISABLED

also try to ssh directly , use PUTTY to create a connection and check with SSH port..

This is not the way to connect a Private Network PC from a Public Network or from the Internet.
Good way is setup VPN service in your computer and open the VPN port in your Router. Then connect your other network PC ( from where you want to connect your server for telnet or file sharing ) using the WAN IP address in your VPN client ( VPN client is like PPPOE desktop ).

Not possible to explain the process, I think it's better to call an expert.

Or use TeamViewer, it's easy to browse your remote computer on your desktop. You can do anything like telnet, file sharing etc etc.

Hey Guys,

Thanks for your replies. I got everything working fine. I did nothing new. I was jus trying from my PC itself. It seems my modem/router didnt support loopback. I tried from a different network everything worked fine.

About the VPN I will try to use that. and I don feel there is any security threats in this. Coz, the port im opening is only to my virtual server. Im sure there is no way to play around with these servers.

Thanks again.
Jo

Thanks Guys.

Please find the steps below. These would the steps if you want to host a server from your home to accept only telnet/SSH connections.

Step 1 : Install the appropriate server properly, in my case virtual emulated server ( Alpha server for Openvms )

Step 2 : My setup is

UTSTARCOM WA3002-G1 Mode/Router
|
|
v
5 port switch
|
|
v
One PC with 2 ethernet cards.
For windows - Dynamic IP : 192.168.1.33
For Alphaserver - Static IP : 192.168.1.39


Step 3: Login to the modem and go to advanced setup --> NAT --> Virtual server

In the application select telnet / telnet and for local port gave 192.168.1.39 and save

You are done


Now its not possible to find the Ipaddress of I'm modem, if you are away.

So I registered a host name for free in "dyndns.org" and updated all those information in the modem under
Access management --> DDNS

Now, where ever I am, I will just telnet my hose name

ex: telnet joslovefun.jose.net

I will get login prompt of my server.

Hope this helps
