OpenVPN - Disconnect after about 5 minutes since activating IPv6

[theq86]

Hi,

Yesterday, I managed to get my DualStack configuration to work. Since then, about every 5 minutes after connecting, the service restarts with error: event_wait : Interrupted system call (code=4)

I strongly assume my IPv6 configuration causes the problem. If I disable IPv6 everything works fine again.

I can't find anything else in the logs to get the root cause. Has anyone any idea ?

Edit: The error occurs, when my WAN interface has an IPv6 address set. Even if IPv6 is enabled but WAN has no address set (i.e. if I checked to get a prefix only) the vpn connection is stable. It's just the fact my WAN iface has an IPv6 address...

Okay, problem is not directly related to OpenVPN service.
Problem is, that every 15 minutes the newwanipv6 script restarts the vpn server. however, there is no new wan ip. so why is it constantly triggering this?
