[Openswan Users] Re-establish tunnel after WAN outage

[Frank Murray]

Thanks David,

That worked perfectly - I'm using Openswan 2.6.22 on a 2.6.31 kernel.

BTW I see that you work on Snapgear. I currently use it on an Intel IXP425 platform and found the build environment to be very elegant and flexible. I didn't come across any public forums where Snapgear was discussed though so can you point me in the right direction?

Cheers,

Frank

I'm using DPD to detect that the gateway is no longer present and this give me the option to place the sa in 'hold' mode or to clear the 'sa'.
