0000438: IPsec VPNs closed after reboot
After rebooting Endian, all the net-to-net VPNs show status as "Closed". Clicking on "Save" in Global Settings starts most of them, but usually a few will require a restart.
Problem experienced on two different sites. Logs attached.
No tags attached.

this happens only directly after reboot, correct?

Because the error message tells me that the uplink is not yet up correctly, so ipsec is not able to find the default gateway.

After the uplink is up, does *this* ipsec connection work when you start it manually?
2008-01-10 11:14   
Correct. On both sites, all VPN connections show status as closed after reboot and will remain that way until I restart them. Clicking on save or just restarting one of them is enough to bring most, if not all of them up. Once they are open they seem to be as reliable as previous versions.

ah, great
so this is a timing problem
ipsec needs to wait a little bit longer on boot until the uplink is really up.
will fix it.

I should add that both sites use fairly fast PCs (one is a P4 2.3GHz, the other is Core 2 Duo) in case that has any bearing on the timing issue.

happens because /etc/uplinksdaemon/mainchanged will be triggered *before* /etc/uplinksdaemon/addrchanged

but the default gateway will be set in addrchanged and ipsec will be restarted during mainchanged, so ipsec starts without a default gateway set.
