[Solved] Setting a public IP

allymac11 · 2017-12-29 02:10:02

Hi Guys,

I currently pay my ISP for 1 static IP and i thought it'd cool to assign to my Arch machine
I have DMZ'd and set up NAT in my router config. Then assigned it to an the adapter... However i'm unable to ssh in for an external network.... Do I need to configure something in the IP tables (I know the exist but don't really know alot about them thats why i ask) ? any advice would be appertained

Cheers
Ally

What is "the adapter in my Arch machine"?

allymac11 · 2017-12-29 02:22:08

its an ethernet adpater

You need to forward the port from your router and make sure the port is open on your machine (and sshd is configured and running).

And start by proving you can connect to your ssh server from within your private network. Then do as Jason says and forward the port.

And, cool though it may be, be aware you are opening yourself to attacks. Don't believe me?

Be certain your system is locked down with hard passwords for all accounts as an absolute minimum. Even better, don't allow ssh password logins -- insist on asymmetric keypairs. Still better, run something that actively looks for attacks and blocks the attacker at the firewall.

But... why is ssh running on port 22? I've never seen a reason to do that in publicly facing IPs (not to mention I normally have too many machines behind a single IP anyway).

"It doesn't matter" - moving ssh from port 22 will just filter the most inept attacks. The relevant bit is to deny password logins.
Intrusion detection will keep your network responisve.

Another approach is to only allow certain IP ranges itfp. If you know you won't use this from an (who hacked the election? ;-) IP, there's no reason to allow it anyway.

Okay guys i got it working!!! It was a rookie mistake on my part.. Because I'm running the Arch instance on a VM all i had to do was assign a secondary NIC and set the network connection type to NAT and it worked!! next step like ewaller suggested i'll set up my asymmetric keypairs thanks again for the help guys look forward to being apart of the community!
