My last router used IP range 192.168.1.1-255 with subnet mask 255.255.255.0. I've got a new router, but this one used a IP range 192.168.10.1-255, with the same subnet.

I can't ping or access the server by its host name anymore. Its connected to my router, so maybe I can change my IP of my pc to 192.168.1.something, 123 for instance, and then login to change that IP?

Or do I need to pull it out of the closet and attach a screen, mouse and keyboard to it and do it manually?

  • a) If server's IP is static, configure your new router's LAN to 192.168.1.0/24, or, backward, your server to 192.168.10.0/24; b) I can't ping or access the server by its host name anymore - from Lan or from Internet? If last - configure prot mapping or ВЬЯю

If the server has a statically assigned IP address (on the host, not in the router/switch config), then yes, you will need to do it manually. You cannot access a x.x.1.x address from a x.x.10.x network with your current setup.

You can likely change the subnet your new router uses from x.x.10.x to x.x.1.x if you're feeling up for it, and the firmware supports it.

  • No :(, my (sucky router) does not support changing subnet. And its statically defined on the server. Its like a maxi tower inside the closet... there goes the weekend :P Meh :D

What I did since the server had a static IP assigned in the properties for the connection (Windows server), I took my laptop and assigned a static on the same subnet. So if the server was assigned 192.168.1.55, with my new router dishing out ips on 192.168.10.100-255, I could manually set my laptop to 192.168.1.123, and BAM - contact! I was able to remote in, change the IP of the server to the new subnet and assing my laptop back to DHCP :D Problem solved.
