We recently implemented vpn-filters vpn's on a Cisco

Customer Question

We recently implemented vpn-filters for l2l vpn's on a Cisco ASA5520, after we did we noticed some weird issues, where it would drop the connection for the vpn traffic for 1-2 minutes, but only from the remote site, during that time you could ping/connect from the central site to the remote site.
Do you know of any reasons why this would happen when using group policy and vpn-filters?

Hello my name is***** should be able to assist you.Are your users or some of them using the same usernames to login to the vpn?

These are l2l vpn's, not soft vpn's.

You've probably already done this, but have you reviewed the logs for the routers to determine if it sheds any light into it?I saw group policy and there is a setting in there that made my brain go straight to per user authentication. Richard

I'll review. I was hoping to see the vpn connection dropping. Since you stated that you are still available to ping then you ruled out the possibility of the Wan connection going down. Let me review and I will help you get to the bottom of it. If I can figure it out, we can pass it along to someone else here that might have worked with tha router before.Thanks,Richard.
