ASA 5505 Site to Site VPN keep dropping

[leonnikolaou]

Hi all,

I have an issue with my site to site VPN.

I have 4 sites connected  to my main HQ site via Cisco ASAs 5505 firewalls. The problem is that once and then the sites disconnected from my main site. This disconnection is not happening at the same time for the the 4 sites. For example, it might be different site each time disconnected.

Could you please advice any suggestions. Let me know if you want to post the firewall's configurations.

Thank you for your time

Basically should configure idle/session timeout value to none.

Checkout the section -Verify Idle/Session Timeout in given link.

Hi Ajay,

Thanks for your advise. I have just did that (see sceenshot below).

Let's wait sometime to see if it stops dropping the connection.

Thank you for your help

Hi,

Regarding the above issue, the site-to-site vpn connection still keeps dropping.

I have attached for you some logs and configurations in order to have a better view.

x.x.138.1 - HQ site

x.x.x.241 - Branch 1

x.x.139.253 - Branch 2

** I have attached configuration of two branches and the HQ site.

Thank you.

I have check almost everything from my firewalls side but couldn't find anything wrong. My ISP said that everything was fine from their side (as always says ) but after insisting that the problem is due to their DSL connection problem seems to fixed (so far, so good, cross fingers).
