I have two Cisco ASA's running code 7.2(2). I'm migrating the vpn from one of the devices from an old firewall to the new ASA. The new vpn is working fine, but the ASA box had the following lines from the previous vpn: tunnel-group 207.190.202.66 type ipsec-l2l tunnel …
1. First – you need to understand a couple of things, for a VPN to work, it needs the IP address of the “Other End” of the tunnel in two places. a. In the Cryptomap. b. In a Tunnel Group. 2. First lets find the cryptomap, connect to the ASA, log in go to enable mode then configuration mode. Suppose for some reason you wish to have the ASA send a constant ping to something. This could be helpful to keep a tunnel alive, or send constant ping for some reason. This is actually required when making a VPN tunnel to Amazon AWS. Suppose we want the ASA to ping 93.184.216.34 every 3 seconds with a 1000 milliseconds (1 second) timeout.

The Cisco ASA supports VPN filters that let you filter decrypted traffic that exits a tunnel or pre-encrypted traffic before it enters a tunnel. You can use the VPN filter for both LAN-to-LAN (L2L) VPNs and remote access VPN. Jul 14, 2020 · The Cisco ASA with FirePOWER models 5506-X, 5506W-X, 5506H-X, and 5508-X support Easy VPN Remote as a hardware client that initiates the VPN tunnel to an Easy VPN Server. The Easy VPN server can be another ASA (any model), or a Cisco IOS-based router.
There are a couple main parts of any client VPN configuration on an ASA. Two of the core configuration components are tunnel groups and group policies (crypto maps are a key part of IPSec based L2L and Client VPN’s but aren’t relevant with SSL VPN so I wont be discussing them at this point). Tunnel Groups
Oct 29, 2009 · Re: Clear VPN Tunnel phase1/phase2 If its an ASA, you can also teardown specific tunnels using their index numbers. To get the index number do "show vpn-sessiondb <(l2l,remote,svc,webvpn)>" command Hi, clear isakmp sa alone will bring down or clear all active l2l ipsec tunnels including ra vpn tunnels as well. if you want to disconnect or bounce specific l2l tunnel specify the peer address: clear crypto isakmp sa . once you brake that particular tunnel you can re-start it by just sending interesting traffic again. Regards WARNING: This will reset ALL ISAKMP VPN tunnels (both site to site, and client to gateway).. Cisco ASA Reset One VPN Tunnel. 1.
