All, we are an MSP and we have VPN tunnels to most of our clients networks, These are setup in one of several ways, ASA to ASA, ASA to Pix, ASA to Concentrator or Concentrator to Pix, Concentrator to Concentrator, Concentrator to ASA.
Right now all of these tunnels allow for 2 way communications. We would like to change that to allow us to access our clients but our clients to not access us. I've seen a number of posts of people wanting to undo this so I'm hoping someone knows how to do it. Ideally i'd like to just do this on our end in our ASA and Concentrator so I don't have to modify upwards of 60 client firewalls but if I have to do it on everyone so be it.
Thanks in advance!!
