Site to Site (IPSEC) vpn connections restart

IPsec, VPN, PIX

Hi,

I'm arvind from India. I'm using IPSec VPN for site to site communications between PIX 515 and Nomadix Gateway. I'm accessing the pix through the PDM. When ever I change any configurations in pix immediately some sites are getting down. Immediately, i used to check some commands in pix, after 2 hrs or less then 3 hrs all sites were got up automatticaly.

show crypto isakmp sa (result is
&
show crypto ipsec sa

What things are getting restart in pix & why its happening.

Pls. guide me to troubleshoot the problem.

thanks,

These particular commands should not be shutting down any VPN sessions as all you are doing is looking at the status of any security associations. Something else must be happening around this same time that you are in this device. I'm not sure I would recommend using PDM to manage this device. Not all features are readily accessible in the PDM. Try using these same commands from an SSH session and see if the problem still exists. Try turning on debug and capturing any logs to show what might be happening.
