You can restrict access to the Administration Server or your
web site based on which computer the request comes from.
You can restrict access to the Administration Server or your
web site based on which computer the request comes from.
If you select the Only from option, enter a wildcard pattern
or a comma-separated list in the Host Names or IP Addresses fields. Restricting
by hostname is more flexible than by IP address: if a user’s IP address
changes, you won’t need to update this list. Restricting by IP address,
however, is more reliable: if a DNS lookup fails for a connected client, hostname
restriction cannot be used.
You can only use the * wildcard notation
for wildcard patterns that match the computers’ host names or IP addresses.
For example, to allow or deny all computers in a specific domain, you will
enter a wildcard pattern that matches all hosts from that domain, such as *.sun.com. You can set different hostnames and IP addresses for
superusers accessing the Administration Server.
For hostnames, the * must replace an entire
component of the name. That is, *.sun.com is acceptable,
but *users.sun.com is not. When the * appears
in a hostname, it must be the left-most character.
For example, *.sun.com is acceptable, but users.*.com is not. For the IP address, the * must
replace an entire byte in the address. For example, 198.95.251.* is
acceptable, but 198.95.251.3* is not. When the * appears
in an IP address, it must be the right-most character. For example, 198.* is acceptable, but not 198.*.251.30.
