Setting up OWA access outside ASA

mmricisco — Fri, 21 Feb 2020 08:50:23 GMT

We had an instance of OWA setup through our old PIX that would allow users to use it through the Internet, rather than having to login through VPN and then accessing it.

Turns out having to login through VPN and accessing OWA is not a desirable option to our management. Does anyone know if the setup for OWA access on an ASA box is much different than the PIX? Here are the entries on the 515 that would relate to this type of connection:

access-list acl_out permit tcp any host 12.27.89.67 eq smtp

access-list acl_out permit tcp any host 12.27.89.67 eq www

static (inside,outside) 12.27.89.67 172.21.221.7 netmask 255.255.255.255 0 0

It depends on your particular scenario. Are they doing Web mail? 2000 or 2003? Check this link out.

if you using https then you need to do the following

1. access-list acl_out permit tcp any host eq https

2. static (inside,outside) tcp https https netmask 255.255.255.255

i would recommened using https over www here is the link on how to setup https for OWA on exchange
