We have a number of customers who cannot properly transmit files to use via HTTPS since we moved from the PIX 6.X to the ASA 7.X system.
The servers in question are connected to a CSS 11051. When we moved to the ASA, a small but significant number of customers using Linksys BEFSR81 and BEFSX41 routers are unable to transmit files to us via HTTPS. They can connect, and they can retrieve files from us, but when they transmit data using the call HttpEndRequest the connection times our with error 12002. I turned off NAT-Control but no luck.
This has impacted enough customers to generate concern in upper management. Does anyone have any idea why the ASA would behave differently than the PIX 6.X, and is there a way to correct it on the ASA so that these connections can be completed. We can't ask this many customers to change out the SOHO firewalls to accomodate our changing our own firewll.
Any help is greatly appreciated.
