Frequently Asked Questions
Q: Is it possible to limit the Web portal to a certain network segment for testing
purposes?
A: By default all subnets are open to the published applications. However, the portal
can be set up to limit the published applications to a set of subnets. It can be
benefi cial to implement this, as isolating certain applications during testing periods
is necessary in order to make sure all endpoint policies are confi gured correctly.
Q: A few end users have reported that some published applications are grayed out on
the Web portal and they cannot click to use the application.
A: Endpoint policies have been designed to govern which rules on managed or
unmanaged devices the end user. must adhere to. The ???access??? endpoint policy has
two options for noncomplying clients: grayed or invisible. This can be achieved by
accessing the published applications property page.
Q: Why should I choose IAG Server instead of an ISA server only?
A: On top of all the advantages ISA server will bring to the organization, IAG has
the added advantage of granular policy control, advance security and manageability
control, access from unmanaged PCs or mobile devices on unknown networks,
and strong endpoint security.
