I have a question. Im setting up a server that supports OWA and outlook anywhere.
I have a asas 5505 that i want to set up with SSL vpn so that remote users can launch Remote desktop and access their own computer in the office. When i go to https://asa5505outsideip i go to the iss menu.

Any input?

I have not done the modifications to the asa yet but the example from cisco says that i should go to
https://externaipoftheasa when i am finished with the setup to get ssl vpn access-

But when i try to go to that site today i get to IIS and i was wondering how i would work around this?
I still need the OWA to work, so i can disable the entire IIS

Do you have a static NAT pointing external traffic to your IIS box?

The best thing would be to configure the ssl vpn on a nonstandard port. I usually use port 1025 for all installations.

publish OWA on the Clientless portal? you should ony have a problem if you need Direct Push EMail or if you need to forward Https - because once you enable webvpn on the outside interface you cannot forward https.

The only way round that problem is to have another external interface (which means having a security plus licensed firewall)

>>so that remote users can launch Remote desktop and access their own computer in the office. When i go to

yeah you can do that as well from the portal - there is a Java RDP applet that you can use to RDP straight from the portal

You can run the VPN on a different port, say 444 and still forward 443 to the OWA server
Then for vpn you access it by https://outsideip:444

You can use the self-signed cert. Users will get warnings, but can either ignore them or install the cert into the trusted root list on their pc.

If using ASDM, under Configuration | Remote Access VPN | Clientless SSL VPN Access | Connection profiles
In the right pane, see  Access Port: [443  ]   <== change the port here
