[Openswan Users] Routing Issue

Fri Jun 8 11:18:03 EDT 2012

Everything checks out fine in the logs.

i want to have a better understanding.

the dpddelay and dpdtimeout .. if you increase this or decrease these
follows what does it really do?

I noticed that all of a sudden i had 3 tunnels, and then back down to
2 tunnels which i should have. BUT my routes stayed. this is testing
if i restart the service on the client side. IF i reboot the client
then thats when the routes drop and never come back even thou on the
client the routes come up. the server side it never stays. is there a
way to just keep the route even if it drops for 1 hr lets say or 1
day, would the dpdtimeout or delay be something i want to increase to
24 hrs or something? i think i would eventually end up with like
10000's of tunnels but the delay would kill the tunnel since this is
the actual keepalive delay? i just want to see if i can understand it
better.
