I’m experiencing a weird behaviour on my server.
It is a virtual machine, running on ESXi which is hosted on a “so you start server” from OVH.
i want the virtual machine to have two network adapters: one that links to the internal LAN, and another that goes to the internet (outside) using OVH IP failover system.
Howerver, when both interfaces are running simultaneously, the server’s connexion to the internet is unstable on WAN and LAN. Sometimes it can ping the outside (google.com) and the next minute it can’t.
Here’s the content of /etc/network/interfaces
# This file describes the network interfaces available on your system # and how to activate them. For more information, see interfaces(5). # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.110.110.199 netmask 255.255.255.0 network 10.110.110.0 broadcast 10.110.110.255 gateway 10.110.110.254 # dns-* options are implemented by the resolvconf package, if installed dns-nameservers 220.127.116.11 dns-search qwerteach.com auto eth1 iface eth1 inet static address my.wan.ip.xxx netmask 255.255.255.255 broadcast my.wan.ip.xxx dns-nameservers 18.104.22.168 post-up route add ovh.gw.xxx.xxx dev eth1 post-up route add default gw ovh.gw.xxx.xxx dev eth1 pre-down route del ovh.gw.xxx.xxx dev eth1 pre-down route del default gw ovh.gw.xxx.xxx dev eth1 up route add -net 10.110.112.0 netmask 255.255.255.0 gw 10.110.110.254
where ovh.gw.xxx.xxx is the custom gateway ovh requires to use the ip failover (as described here)
Thanks in advance!
netmask is wrong. Though, it’s not your fault; the OVH guide is wrong too. The
netmask should be set to
255.255.255.0 and the
post-up route add and
pre-down route del lines should not exist.
