You can also select which ICMP messages will be accepted on the Internet interface. Destination
unreachable ICMP messages will always be accepted. For example, disallowing echo requests will
mean that your SnapGear VPN Router will not respond to pings on its Internet Interface.
The SnapGear VPN Router's web administration pages are usually accessed on the HTTP default
port, that is, port 80. Changing this port number is advisable if you are allowing Internet access to
web administration pages as this will hide your web administration pages from a casual web server
who happens across your SnapGear VPN Router on the Internet. Note that after changing the web
server port number, you must include the new port number in the URL to access the web
administration pages. For example, if you change the web administration port number to 88, the
URL to access the web administration will be similar to http://192.168.22.1:88.
External Access to Services
The SnapGear VPN Router's firewall on the Internet interface can be configured to accept or deny
external requests on a specified incoming port, based on the originating (source) IP address.
