They have version 8.2 now and we want to get the more stable newest one. Can we get an 8.6 version? or we need an ASA 5500X for that one?</P><P>Which one do you recomend? </P><P></P><P></P><P>Regards</P><P></P><P>Mariano</P> Mon, 11 Mar 2019 22:52:05 GMT https://community.cisco.com/t5/network-security/asa-firmware-version/m-p/1922544#M457221 Mariano Suarez 2019-03-11T22:52:05Z ASA Firmware version https://community.cisco.com/t5/network-security/asa-firmware-version/m-p/1922545#M457222 <HTML><HEAD></HEAD><BODY><P> Hi </P><P></P><P>you get upto 8.4 for the ASA 5520</P><P></P><P>8.5 and above are not supported on this platform.</P></BODY></HTML> Mon, 09 Apr 2012 19:02:27 GMT https://community.cisco.com/t5/network-security/asa-firmware-version/m-p/1922545#M457222 Amit Rai 2012-04-09T19:02:27Z ASA Firmware version https://community.cisco.com/t5/network-security/asa-firmware-version/m-p/1922546#M457223 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P>Also take into consideration that NAT has been totally rewritten from 8.3 onwards. So the format you have been using up to 8.2 will change. This change also reflects to to the access-lists.</P><P></P><P>We are currently using 8.4(2) in most of our production environments. Also 8.4(3) in some of the newest ones.</P><P></P><P>As for the stability I can only say that we have not yet had any problems with the software version mentioned above.</P><P></P><P>- Jouni</P></BODY></HTML> Mon, 09 Apr 2012 19:08:26 GMT https://community.cisco.com/t5/network-security/asa-firmware-version/m-p/1922546#M457223 Jouni Forss 2012-04-09T19:08:26Z
