Specifying the MAC Address on a Server
The MAC address is entered as a text string in the database of the authenticating server. This text
string must follow the format sent by NetDefendOS and this is a series of six hexadecimal two
character lower-case values separated by a hyphen ("-") character. For example:
00-0c-19-f9-14-6f
Dealing with Duplicate MAC Addresses
If there is a router between the firewall and connecting clients, NetDefendOS will receive the
same MAC address from the router instead of the original client MAC address. This causes
problems because NetDefendOS is set up by default to not allow clients to duplicate MAC
addresses.
The problem is solved by enabling the property Allow clients behind router to connect for the
relevant authentication rule.
