Clients with MAC pass thru on Captive Portal can't email attachments, times out
For some reason clients with MAC pass thru on Captive Portal can't email attachments, times out generally with the email showing it is about 40-80% complete. If I remove their pass thru MAC address and make them log in then they can email without an issue. Does anybody have an idea what might cause this? Thank you.
