I have an ASA 5505 and 5510, both running 8.2.5. Is it possible to configure these things to redirect all HTTP traffic to Websense Cloud Web Security? I know you can do it if you have an internal websense appliance, but I can't figure out how to get the ASA to forward traffic to an external proxy.
If I use the following command:
ASA(config)#url-server (outside) vendor websense host x.x.x.x timeout 15 protocol tcp version 4 connection 10
it tries to redirect the traffic to port 15868 on the Websense host (because this is the default port on which a Websense web security gateway would accept incoming connections), but Websense Cloud Web Security uses port 8081. So at minimum, is there a way to change the target port number that the ASA uses for sending proxy traffic? If so, would this work?
I know it's possible to do with later version of the asa software, but I really don't want to upgrade if I can avoid it.
Thanks.
