Hi all,

been working on this for weeks now, cant believe i still haven't found a solution, heres a bunch of details about the setup and the problem:

externally connecting to, i get diagnose connection problems

internally goes straight through no problems

i have setup a mail publishing rule enabled form based auth on that only and have removed form based from exchange

the isa server and exchange are on the same box

i have setup a entry in the hosts file on the server to go to isa servers address

isa doesnt have an external address it has a internal address on a different range and ports 443 80 and 25 are forwarded to that address range, all works fine with that no problems ( sees me on 443 fine)

in the isa logs there is no external ips logged i only see our internal addresses

using my iphone to browse to
i get asked to accept the certificate i do then i get page cannot be displayed
and using IE as above get that error message when i diagnose

oh and a telnet on 443 externally works fine too

p.s. i used my iphone to browse externally as active sync doesnt work yet either (im guessing an underlying problem with owa might solve both problems)
