I have an ASA5505 at home that I use for VPN access. Occasionally when I connect I can't ping anything. I check config and it shows:</P><P></P><P>no crypto isakmp nat-traversal</P><P></P><P>I've configured "crypto isakmp nat-traversal" so many times before and somehow it still gets removed. Seems to happen randomly as well as when the device is rebooted. (yes the config has been saved). I'd say this happens at least 2-3 times a week.</P><P></P><P>Any ideas? I'm running 8.0.2 code.</P> Fri, 21 Feb 2020 11:00:39 GMT https://community.cisco.com/t5/network-security/asa-5505-crypto-isakmp-nat-traversal-is-gone/m-p/1095945#M418889 jake-savage 2020-02-21T11:00:39Z Re: ASA 5505 - crypto isakmp nat-traversal....is gone? https://community.cisco.com/t5/network-security/asa-5505-crypto-isakmp-nat-traversal-is-gone/m-p/1095946#M418890 <HTML><HEAD></HEAD><BODY><P>It is a bug.
