in Help

Hello all,

I have problems with gre tunnel. I followed buyvm tut and was working for ~8 days and today it is not responding gre tunnel on my game servers. The vps was not restarted but it stopped working. Then I tryed to add again command but nothing. Then I added to rc.local all comands and restarted but still not working. Also tryed to ping 192.168.168.2 but nothing...

Can someone help maybe?

This is for gre vps

echo 'net.ipv4.ip_forward=1'>>/etc/sysctl.conf sysctl -p /etc/sysctl.conf iptunnel add gre1 mode gre local 51.254.xxx.xxx remote 195.154.xxx.xxx ttl 255 ip addr add 192.168.10.2/30 dev gre1 ip link set gre1 up iptables -t nat -A POSTROUTING -s 192.168.10.0/30 -j SNAT --to-source 51.254.xxx.xxx

Other server

iptunnel add gre1 mode gre local 195.154.xxx.xxx remote 51.254.xxx.xxx ttl 255 ip addr add 192.168.10.1/30 dev gre1 ip link set gre1 up echo '101 ATGRE'>>/etc/iproute2/rt_tables ip rule add from 192.168.10.0/30 table ATGRE ip route add default via 192.168.10.2 table ATGRE

Ports are opened

GamePanel - Started server on 192.168.10.1:7777, with maxplayers: 50 lanmode is OFF.

And it should start on 51.254.xxx.xxx:7777
