The SnapGear appliance’s Web Admin pages are usually accessed on the default HTTP
port (i.e. port 80). Change the port number if you are allowing Internet access to the web
administration page. This will hide your web administration pages from casual web
surfers who finds your SnapGear appliance on the Internet. After changing the web
server port number, you must include the new port number in the URL to access the
pages. For example, if you change the web administration to port number 88, the URL to
access the web administration will be similar to http://192.168.22.1:88.

External access to services

The following figure shows how to configure external access to services:

Figure 6.2 Configure external access to services

The SnapGear appliance firewall on the Internet interface can be configured to accept or
deny external requests on a specified incoming port, based on the originating (i.e.
source) IP address.

This is useful for restricting external access to the SnapGear appliance's services (e.g.
telnet on port 23) to trusted external IP addresses only. The options specified in the
Administration Services section for disabling web or telnet access on the Internet
interface have lower priority than any rules you specify for web or telnet access in this
section.
