Description
Select to enable or disable UDP filtering here.
Select the authentication method used here. Options to choose from
are MD5, CHAP, PAP, MS-CHAP, and MS-CHAP-v2.
Select the virtual IP option used here. Options to choose from are
IPv4, IPv6, and URL.
After selecting IPv4 as the Virtual IP, the following field will be
available. Enter the virtual IPv4 address used here. All JWAC
authentication processes communicate with this IP address, however,
the virtual IP does not respond to any ICMP packets or ARP requests.
So it's not allowed to configure virtual IP in the same subnet as the
switch's IP interface or the same subnet as the host PCs' subnet,
otherwise JWAC authentication cannot operate correctly.
The defined URL only takes effect when the virtual IP address is
configured. The users get the FQDN URL stored on the DNS server to
get the virtual IP address. The obtained IP address must match the
virtual IP address configured by the command.
If the IPv4 virtual IP is not configured, the IPv4 access cannot start
JWAC authentication.
After selecting IPv6 as the Virtual IP, the following field will be
available. Enter the virtual IPv6 address used here. If the IPv6 virtual
IP is not configured, the IPv6 access cannot start a JWAC
authentication.
