Hi guys. I am relatively new to PIX/ASA and am still learning my way around it. The thing is I came into a company where the IT infrastructure is pretty much setup already and management wishes to retain the current setup and are only open to small configuration changes in the switch and ASA. We have an L3 core switch which goes through an ASA and out to the ISP provider. We also have an alternative route going to another router. My problem primarily is with https. We have a route map that redirects www packets to a transparent squid proxy but https filtering won't work with squid setup as a transparent proxy. I cannot add route-map sequence to block 443 because there are several https sites that i need to allow for users and we had a cpu utilization concern previously and the cause was the route-map. That leaves with me with only the PIX. I did some further research and there were some mention that the ASA/PIX couldn't filter https traffic. I don't know if this is true. Anyway, I am desperate. Effectively restricting https traffic would require a major reconfiguration of the acls, routemaps and PAT involving several switches and routers.
I would appreciate any assistance and advice regarding this.
