Configuration restrictions and guidelines
Follow these restrictions and guidelines when you configure L2TP-based EAD:
EAD authentication fails if no ACLs or rules are configured on the CAMS/IMC server even if EAD is enabled on the LNS.
The LNS can use different ACLs to filter packets from different iNode clients.
As a best practice, use EAD authentication for iNode clients on the Internet and use Portal authentication for iNode clients on a LAN.
