Centos 5 is also a bit old os. Is it possible to use newer version? (like centos 7 or centos 6?) Eero 2016-02-09 19:52 GMT+02:00 Gordon Messmer : > On 02/09/2016 07:04 AM, John Cenile wrote: > >> does anyone have any suggestions on what the problem might be? >> > > Not off the top of my head, bu

Thanks, I've updated the config with the following: keylife=20m ikelifetime=2h I'll see how that goes. In the mean time, any other suggestions would be greatly appreciated. On 10 February 2016 at 02:14, Eero Volotinen wrote: > Try setting lower keyexpiry time on other endpoint

[CentOS] OpenSwan Drop Out Issue

2016-02-09 Thread John Cenile
