Hi experts. I recently got a 5516-X as an upgrade over our existing ASA 5510. I have configured everything on the 5516-X as per the 5510 ie NATs, static routes, access list implemented on the outside interface for allowing access to servers on specif...

GRANT3779. Thanks a lot. I will add this to my list of things to try in the next scheduled downtime. Hopefully I can get it work this time after two failed downtime attempts where I was only focused on the ASA 5516-X's configuration.
