Apr 30, 2015 · There is an issue with reaching the rekey for the tunnel that may be biting you. It is ASA specific. Here is a link that may help you get pointed in a direction. I have never encountered this issue with ASA to ASA tunnels but I think it is possible that you may have a mismatch. Sep 25, 2018 · IPsec SAs use a derived, shared, secret key. The key is an integral part of the SA; the keys time out together to require the key to refresh. Each SA has two lifetimes: timed and traffic-volume. An SA expires after the respective lifetime and negotiations begin for a new one. Oct 18, 2010 · This document describes how to configure the Adaptive Security Appliance (ASA) to route the SSL VPN traffic through the tunneled default gateway (TDG). When you create a default route with the tunneled option, all traffic from a tunnel terminating on the ASA that cannot be routed using learned or static routes is sent to this route. Sensors promptly sound the alarm. VPN monitoring sensors gather information regarding the VPN connection, such as which users used a VPN to connect (or are presently connected) to the company network and at what time, the type of connection, and the volume of data that is transferred over a certain period.
Sep 26, 2018 · ASA VPN Troubleshooting. Yesterday, I assisted with troubleshooting ASA VPN issues. A local ASA needed to build a site-to-site (aka L2L) IPSec VPN tunnel to a non-ASA third-party. The tunnel was not coming up. The config all appeared to be there, and the third-party said their config was in place too. It’s time to troubleshoot.
The source/destination for the traffic is the public IP for the other ASA. But there is no traffic on the Inside/LAN interfaces of either ASA. I can pull a packet capture off the outside/WAN interface, but it's all VPN tunnel traffic so it's encrypted and I can't see what's actually going on. If I saw a comparable volume of traffic on the
Monitoring tools. AWS provides various tools that you can use to monitor a Site-to-Site VPN connection. You can configure some of these tools to do the monitoring for you, while some of the tools require manual intervention.
