Finding my IP Address

CptnObvious999 · Post by **CptnObvious999** » Mon Oct 24, 2005 4:25 pm

I know this seems like a simple question but I can't figure it out. I am behind a Wireless router (Linksys WRT54G) and I need my global IP address for my computer. When I go to http://www.whatismyip.com it gives me my routers IP Address which I know is my routers because if I run nmap -sS only 2 ports are open: http and https which is for the router administrator control panel. I only have the ipp port open. My local IP is 192.168.1.102 however I think this is only for within my network not for what other people would use to access me. I would like to do a SSH session from my school to my home but I am not sure what IP to use. Can anyone help me out?

You'll need to use your router's WAN IP. You'll have to setup port forwarding -- forward 22 to the internal IP you mentioned.

Got another question relating to networking. I would like to set up DDNS with DynDNS.com but my router is using the http port for its administration control panel so I can't forward it to use my IP. My router has an option to use DynDNS and it successfully routes to my router. I could use alternate port 8080 I think but I want my site to come up when I type the domain without having to specify port 8080. Is there a way to get anything from my dyndns domain to automatically redirected to my computer?

I'm not that familiar with these routers, but isn't access through port 80 to the admin limited to the internal port? The external port has a different address assigned to it. I'm wondering if it would be possible to forward the external port 80 through to your internal network.

I believe Linc has dydns set up this way for his system. Thus, I would have to refer this question to him or another person with more experience on this forum.

I do use dyndns, but I do not use a router. I use a modem, so my ip address to the outside world is actually my second ethernet device on my server machine. I do, however, have to use port 8080, but only because RCN (my provider) blocks port 80.
