Instant Web Publishing Guide

12 FileMaker Instant Web Publishing Guide
Changing the port number on Mac OS X
The first time you enable Instant Web Publishing, Mac OS X requests permission to make a one-time change
to your computer’s setting to facilitate web publishing on a port number below 1024. For security reasons,
Mac
OS X restricts access to ports below 1024. To configure FileMaker Pro to use ports below 1024, you
must provide an administrator password, such as the passphrase created when you first set up Mac
OS X.
You do not need an administrator password to use a port number between 1024 and 65535. For more
information on creating an account with administrator privileges, see the Mac
OS X Help system.
Checking the maximum number of web connections
The number of simultaneous web users allowed to access your files depends on which application you use
to host your database. With FileMaker
Pro, you can host up to five concurrent web users. Use
FileMaker
Server Advanced to share files with more web users.
To view the maximum number of web connections allowed:
1. Open the Instant Web Publishing dialog box (see “Sharing a database with Instant Web Publishing” on
page 9).
2. For Advanced Options, click Specify, then view the Maximum number of connections number.
3. Click OK, then OK.
When the maximum number is reached, additional web users see an error message in the web browser when
they try to access the database.
Important If you feel that you have reached the maximum number of users inappropriately, it’s possible that
a web user has not logged out of the database properly. You can wait for the sessions to time out or close
the file to disconnect web users from the database. For more information, see
“Logging out of a database
and closing a web session” on page 23.
Restricting access except to specified IP addresses
You can restrict the IP addresses that can access your databases on the web. For example, you can specify
that only web users from the IP address 12.34.5.6 can access your databases.
To specify which IP addresses can access your databases:
1. Open the Instant Web Publishing dialog box (see “Sharing a database with Instant Web Publishing” on
page 9).
2. For Advanced Options, click Specify.
3. Select Accessible only from these IP addresses and type the IP address that can access your files.
Separate multiple IP addresses with a comma (,).
4. Click OK, then OK to save the changes.
Note Type an asterisk (*) in the section of the IP address to grant access to web users with similar IP
addresses (for example:
12.34.5.* or 12.*). You can’t type an asterisk in the first section, however.
