The resolution to my problem is to upgrade my ASA image to 8.6.1(5). This resolves bug CSCtq57752. The workaround to the bug is to lower the crypto map's timed lifetime and increase the crypto map's traffic volume threshold:

If you have NAT enabled on the ASA then we need to make sure that traffic between /24 (the local network) and /24 (our remote VPN users) doesn’t get translated. To accomplish this we will configure NAT excemption. ASA 9.5(2)204 and IOS 15.6 were used in my lab. This is similar to the topology used in Policy Based VPN, however there is a slight difference.The connection between the ASA’s and the ISP routers will use subinterfaces, in order to support routing over different interfaces. 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.

Sep 10, 2018 · Another important point for the Phase-2 configuration on the ASA; the security association (SA) can have a lifetime in seconds and in data-volume on the ASA. But Meraki does not “understand” the data volume limit, so when that threshold is reached on the ASA side, before the lifetime runs out, the tunnel hangs for the remainder of the lifetime.

I created Transform-set, by which the traffic will be encrypted and hashed between VPN peers. ASA(config)# crypto ipsec transform-set ts esp-3des esp-md5-hmac! Apply the access list created earlier for matching the interesting traffic. ASA(config)# crypto map vpn 10 match address vpn! I indicated address of Remote2 peer public outside interface. This actually brings us to the end of this series about VPN on the Cisco ASA. In this article, we have looked at the default setting on the ASA that explicitly allows VPN traffic to bypass access list checks i.e. sysopt connection permit-vpn. For pre-7.0 ASA software versions, this command was turned off by default so it had to be explicitly

I'm troubleshooting some issues with a typical L2L VPN using IKE Main Mode w/pre-shared key auth. I'm using an ASA 5550 w 7.2(3) code. I'm trying to find a way to disable the phase 2 security association lifetime kilobytes (traffic volume) rekey value. I know that the ASA will not use this value

Trying to create a site to site VPN with a Cisco ASA 5510 (8.0.3) and PIX 501 (6.3.5). It seems like the tunnel is established correct but the traffic does not get thru. I can see the client connection attempt but no hit on the access-lists when looking at the ASA side. Jun 28, 2013 · ASA(config)# class-map vpn-voice-class creates the class map for voice and ASA(config-cmap)# match dscp ef cs3 af31 matches voice calls and signaling marked by your router before it hits the ASA. Notice that we are also matching only voice traffic over the VPN with this command, A SA(config-cmap)# match tunnel-group your-tunnel-group .

Cisco Certified Internetwork Expert (CCIE) Howard Hooper shares preparation hints and test-taking tips, helping you identify areas of weakness and improve both your conceptual matches against VPN traffic or Qos values. setting connection’s volume and limits, on the traffic by our ASA so we need to increase the size of mtu to maximum size .
