Using another VPSs IP for a VPS

trexos

Hello,

I just bought one of these super cheap VPS with 4 IPv4s. Is it possible to use one of these IPs for another VPS? I think I read something about this. Is this GRE tunneling? Does anyone have a tutorial for Debian?

Thanky you

BuyVM did a tutorial on GRE tunnels here.

Is GRE the way to do that?

Yes it is, you are just passing one servers traffic to another server.. You should also make sure that the servers are close to each other, latency can be a killer.

Okay thank you!

I tried it but I get this error:

root@vserv10:~# iptunnel add gre1 mode gre local IP_1 remote IP_2 ttl 255 ioctl: No such device root@vserv10:~# ip addr add 192.168.168.1/30 dev gre1 Cannot find device "gre1"

Did you fill in IP_1 and IP_2?

Haha yeah sure I did. I checked, iptables are installed as well.
