VPN printer

[pmpesha]

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.
