I've followed this tutorial https://lowendtalk.com/discussion/156850/howto-tunnel-ddos-protected-ovh-ip-to-vms-in-other-datacenter
Commands used both servers:
Server 1
ip tunnel add gre1 mode gre remote 9.176.110.209 local 212.188.100.58 ttl 255
ip link set gre1 up
ip route add 212.188.103.64/30 dev gre1
Server 2
ip tunnel add gre1 mode gre remote 212.188.100.58 local 9.176.110.209 ttl 255
ip link set gre1 up
ip rule add from 212.188.103.64/30 table 666
ip route add default dev gre1 table 666
ip route add 212.188.103.64/30 dev br0 table 666
ip addr add 212.188.103.65/30 dev br0
My intention it's to use 212.188.103.64/30 (.66 / .67 usable) for VMs, at SolusVM (9.176.110.209).
Maybe it's important: IPs 212.188.100.58 and 212.188.103.64/30 are from same subnet for my hosting provider (this means I can use all of them if I choose netmask /22 at IP config).
Actually I can't ping and can't be pinged outside of VM.
Thank you!
** IP addresses are fake!
Edit:
Network configuration used for VM:
IP address: 212.188.103.66
Netmask: 255.255.255.252
Gateway: 212.188.103.65
I can ping internally those 3 servers (nodes + VPS) but nothing outside.
I guess it's something wrong with routing somewhere because it takes about 20 seconds to connect from any node with telnet to VM ssh port.
