Hi,

so i set up two openvpn Tunnels and bonded them together. My goal was to achieve a quick failover in case the Primary connection goes down. However it takes about a minute or so to actually switch from A to B.

Does anybody know why it takes so long?

A: LTE, VPN00, Primary
B: 3G, VPN01, Secondary

There seems to be a bug when "ICMP failover checking" is enabled.

However without ICMP failover checking it is pretty much unusable. Sad

Does somebody know where to change the MII Polling Interval in Zeroshell?
found it: /root/kerbynet.cgi/scripts/mkbonddev
Or not, it does not change after saving it and restarting the bond.
fixed: [you have to recreate the Bond]


I am on 2.0 RC3, does somebody know if the bug got fixed in 3.0?

On the server the mii status stays up, on the client it is down.

So that is why it cannot work. Did anybody fix this problem?

It turns out the virtio nic driver was causing problems.
