Reestablish IPSEC tunnel VPN on Cisco ASA 5505

All router and switch devices occasionally have to be rebooted in order to keep traffic flowing.

It’s the same when it comes to VPNs as well. Below is how to restart the IPSEC tunnel on a Cisco VPN.


  1. SSH or Telnet into your Cisco Device.
  2. Type in the following command once logged in: clear ipsec sa peer <remote-peer-ip>

The connection should now restart and be reestablished.
