Re: Unable to connect through MS ISA2004 server Oddly, I spent today from behind an ISA 2004 server (which is behind FW-1) to connect to a test Connectra NGX R61 box that's on a cable modem on the Internet (my R60 to R61 upgrade test box). When I did this same thing to Connectra NGX R60, I got the same proxy prompt and could enter my credentials as "domain\user" and get through ISA (I do require authentication through ISA). I haven't gotten it once connecting to Connectra NGX R61 with its version of the SSL Network Extender. One of the fixes in Connectra NGX R61 is improved authentication through proxy servers, yet you say ISA does not require authentication. Do you know what version of Connectra they're using? Ray |
