Exchange Web Outlook through Captive Portal

[outtasking]

Hi,

I´ve set MAC filter to pass-through the captive portal .

When I enable the captive portal in the LAN , I can browse many sites, but not a web Outlook which is using some VPN or citrix client.

However, If I disable works fine, so pfsense is properly setup in terms of firewall rules .

What can be the issue ?

Thanks
