I have an external facing sharepoint site , thre are two type of users
Internal users and external users
Internal users = all employees who have AD accounts , employees are able to checkout documents when they are either using the VPN or in the Network , but once they are out of the network or not on vpn they get an error
if user on network they dont have to go via the TMG and can access the site using http
but if you are not on the domain or vpn then the user has to go via tmg and it uses https
is this something to do with the port ?
It happens across all browsers (IE , firefox Chrome)
SharePoint 2010 -- config
2 WFE's -- 1 app server 1-- sql server
TIA
