The Security menu allows you to configure a number of settings, including:
Internal Firewall Setup
As an additional layer of protection, the ServSwitch can use an internal firewall.
When this feature is enabled, connections will only be accepted from listed hosts.
For example, the administrator can type in
10.1.0.1/240
in the “Accept” field.
The IP of the client’s computer between 10.1.0.1 and 10.1.0.240 allows accessing
the ServSwitch with the right username and password. On the other hand, the user
can type in 192.168.1.0/20 (for example) in the “Reject” field. The IP of the
client’s computer between 192.168.1.0 and 192.168.1.20 will be rejected to access
the ServSwitch. This makes the ServSwitch invisible to them.
There are 3 ways to type in the IP addresses:
1. Specific IP addresses (for example,
10.1.0.1
,
10.1.0.5
, etc.).
2. Net Range (for example,
10.1.0.1/240
)
.
3. Host Names (for example,
yahoo.com
,
google.com
, etc.).
CAUTION
Be careful NOT to lock yourself out! Be certain that your IP will be
accepted by your filter.
