can fortigate do these

[student1363]

hi,

I am going to buy a fortigate 100 series (not decided specifically on model). What I really need to know is whether it support "reverse proxy" or not. I want it between internet and my webserver (I know about the foriweb, but I am tight in budget and want other fortigate features like IPS as well).

Another question is, does fortigate need any license for HA?

my last question is, can fortigate get authentication info from users ( for services that need it like email or sharepoint) and give it to server; if authentication was successful user will be directed to server.

thanks in advance
