Hello,

If this is more of a server issue, please respond so that I can move it to the "server" section of the site.

Anyway, I've recently set up a dyndns account that connects to my home server on my network. I used a tutorial the other day that allowed me to set up a cronjob that would update dyndns ever so often.

Today, when I tried to connect to the server from school, the connection would not respond, and would eventually drop -- I figured that my server turned itself off, but this was not the case. I got home to find that my server had changed it's internal network IP from 192.168.0.2 to 192.168.0.3. SSH forwarding (from my router only goes to 192.168.0.3 now). I was wondering how it would be able for me to set up an internal static IP that goes from my router to my server (so that my server's IP never changes) and that my dyndns hostname will always make sure it connects to the server no matter what (because the internal network IP will always stay the same).

I was talking to a friend that told me that cronjobs are not responsible for a service that updates my router ever so often to tell it to forward port 22 to a different internal IP (the location of the server).

Any thoughts on this would be greatly appreciated! Thanks!

I let my router a Netgear WGR614v6 handle static ip assignment via the lan IP setup. It assigns the IP I want it to have based on the MAC address of the Ethernet card. The router also handles updating www.dyndns.org when my isp changes the external IP. May want to look closer at your router setup program. http://louieb.isa-geek.net/ is hosted on a PC siting in my den.

Thanks so much!

I got it figured out due to your advice. On my router (a WGT624)in the Router setup/configure lan webpage (I'm not exactly sure what this is called), there was a LAN config option that I selected. After going here, there was an Address reservation option which allowed me to reserve 192.168.0.3 specifically for the MAC address of the network card that my server was operating from.

Without making me recheck my router's setup I would have missed address reservation.

Thanks again, problem solved!
