[SOLVED] Can't SSH to local ubuntu server after putting it into DMZ mode

So I put the ip of my server in DMZ mode because I am experimenting with hosting a website from home and now I cannot SSH into it.

ok, so... that's a bad thing..? you want help to make that not the case?

Might help to explain what you actually did... sounds like something a firewall widget would do... can you not walk up to the machine, login locally and change it back?

Its working now I guess i just needed to reset the network connection?, I ended up just rebooting the server, I tired ifconfig down , ifconfig up , but this didn't work, I also tried dhclient which didn't work either, what is the best way to ipconfig/release renew in ubuntu server?

Sorry, I didn't get. Can you explain it?

well, you should never be renewing a lease on a server, as a server shouldn't be using DHCP...

I don't understand what is so confusing. ipconfig/release , ipconfig/renew , how to do this on linux, as i mentioned i tried ifconfig eth1 down, ifconfig eth1 up, but this didn't work, i also tried using dhclient which didn't work either, as I already said. I ended up having to reboot the server completely which is what i was trying to avoid.

I want to host a simple website from home, but I do not want to pay for an expensive business account for a static ip. As i understand from my reading so far this should be possible to do. My WAN ip changes once in a blue moon, and my lan ip is always the same 192.168.1.whatever. So i really dont see the point in paying for a business account from my isp, i actually dont mind having to go in and change things if the ip changes.

you wouldn't use the tools directly, but use the wrapper services around them, as that's how the defined configuration files get into the question. I would personally just restart the network service - "sudo /etc/init.d/networking restart"

and accusing people helping you of being patronizing isn't a great idea.
