Dynamix UM-A User Manual page 54

Authentication: The different types of available authentications are:
Auto: When auto is selected, PAP mode will run by default. However, if PAP fails,
then CHAP will run as the secondary protocol. This is the default setting.
PAP: Password Authentication Procedure. Authentication is done through
username and password.
CHAP: Challenge-Handshake Authentication Protocol. Typically more secure than
PAP, CHAP uses username and password in combination with a randomly
generated challenge string which has to be authenticated using a one-way hashing
function.
Automatic Reconnect: When it is checked, the ADSL Router will reconnect a PPP session
when it is terminated by the ISP. If a PPP session is terminated under any other conditions
(i.e. by Disconnect Timeout or manual disconnect), the Automatic Reconnect will not
reconnect the session. This box is unchecked by default.
G. Bridge :
Bridge: Enable to connect the LAN to the WAN (bridge the two connections). This is available in
Bridge Mode only (see Table G). Default is Disabled.
H. IGMP :
IGMP: IGMP (Internet Group Management Protocol) relay/proxy specification and environment,
default is Disabled. IGMP is available in all modes and all encapsulations. Support IGMP
proxy/relay function for ADSL Router, based on the following requirement and cases:
On CO side, there must be at least one IGMP querier (router) present. IGMP querier will
send IGMP query packet. The ADSL Router is responsible to relay these IGMP queries to
Ethernet.
End-user multicast application device sends IGMP report while receiving IGMP query or
being activated by the user. The ADSL Router should be responsible to proxy (that is, change
source IP to ADSL Router's WAN IP) the IGMP report to ADSL WAN side, including all
PVCs. The same case is for IGMP leave packet.
