Greetings,
We hava a VPN printer that our IBM AIX system sends print jobs to. Things do work Monday to Friday but not over the weekend. I have noticed that the tunnel do expire over the weekend due to lack of interesting traffic (the users do not work on weekends). When you issue a ping, the tunnel comes back up and the printer reply on the ping successfully. It seems like the printer alone can not generate interesting traffic. What can I do to make the tunnel stay up over the weekend? Thank you.
Phil.

Hi Pmpesha,
The valid time argument for IPsec security association timeout is from 60 Sec to 86400 Sec ( 24 Hours ) so I dont think even the Max Value would help you for the WeekEnd. I would say set up some CronJob script on one of the Machine to initiate a Connection every 8-12 Hours and increase the crypto Lifetime.
Here's a Link a for more Help :-

Manish,
Thank you for your response. I will create the CronJob and see how that goes. Take care.
