It is possible to install 2 owa on IIS pointing to a single exchange server ?

This is what i want :

1- I want to set the first owa on port 443 with a certificate . My users must type https in extern.
2- I want to set the second owa on port 80 . My users must type http in intern.

no, it isn't dangerous

create the site
http://technet.microsoft.com/en-us/library/aa998946(EXCHG.65).aspx
for the host name use your internal name (ex. exchange.domain.local)

create the virtual directory
http://technet.microsoft.com/en-us/library/bb124435(EXCHG.65).aspx
you will need exchange and public

then go into iis manager and modify the bindings for your default web site to use your external dns name for the host name (ex. mail.domain.com)
