    LAC configuration

    + +

    A static REMOTES LNS configuration can be entered by the command:

    +
    setforward MASK IP PORT SECRET
    + +where MASK specifies the mask of users who have forwarded to +remote LNS (ex: "/friendISP@company.com").
    +where IP specifies the IP of the remote LNS (ex: "66.66.66.55").
    +where PORT specifies the L2TP Port of the remote LNS +(Normally should be 1701) (ex: 1701).
    +where SECRET specifies the secret password the remote LNS (ex: mysecret).
    +
    +The static Remote LNS configuration can be used when the friend ISP not +have a proxied Radius.
    +If the proxied Radius is used, It will return the RADIUS attributes:
