AnyConnect RA VPN in ASA Multiple Mode

[johnlloyd_13]

hi,

i'll be configuring anyconnect for remote access VPN in an ASA5500-X 9.8 code. i tried to search but only see this doc which is on asa 9.6:

https://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-firewalls/200353-ASA-Multi-Context-Mode-Remote-Access-A.html

my questions are:

1) what anyconnect 4.x is compatible for asa 9.8 code? i don't see any compatibility matrix.

2) which is the go-to config? private or shared storage? any config example i can follow?

3) is there a specific license/feature needed? I have AnyConnect Premium Peers applied (total of 4x from active-standby FWs).

The guide you linked is a valid one, even for 9.8.

1. Any AnyConnect 4.x release is compatible. Cisco generally recommends using the latest release (currently 4.7.04056)

2. As noted in the linked guide, we make some settings in system context, put the Anyconnect images into shared storage and then used the user context(s) to individually setup Anyconnect. That last bit is pretty much like it's done on a single context ASA.

3. You get the 2 "AnyConnect Premium" (roughly equivalent to the current Apex type) licenses per ASA for free. If you need more you need to purchase Anyconnect Plus or Apex (or VPN only) licenses just like with any other ASA. You add those licenses via using the PAK plus serial number(s) to get an activation-key from the software.cisco.com licensing portal.

hi marvin,

is this the ONLY file i need to transfer in the ASA flash? users are ONLY using windows.

anyconnect-win-4.7.04056-webdeploy-k9.pkg

also, below is my template. appreciate if you let me know if there's any error in my config.

do i need to transfer the anyconnect image file twice? one to disk0 and another to the private 'virtual flash'?

changeto system

limit-resource VPN AnyConnect 4    <<< I CURRENTLY HAVE 4 ANYCONNECT DEFAULT/BUILT-IN LICENSE
limit-resource VPN Burst AnyConnect 4

mkdir PRIVATE_VPN

copy ftp://ftpuser:ftpuser@172.x.x.x/anyconnect-win-4.7.04056-webdeploy-k9.pkg flash   <<< DO I NEED TO TRANSFER ANYCONNECT IMAGE FILE TWICE?

copy flash:/anyconnect-win-4.7.04056-webdeploy-k9.pkg flash:/PRIVATE_VPN/CUST-X
