There is a site that we are trying to connect to that appears to only accept TLSv1. When we try to connect from broadband, it is fine but behind the firewall it does not load. it looks like TLS is not being permitted. Based on a packet capture, it looks like the client is only trying SSL, which is then denied at the server because it's disabled.
When I try from outside the firewall, it works fine.
What on the ASA could prevent a web client from trying to negotiate TLS?
