Hi All, My aim is to authenticate all end points (both registered and not registered) using the PrefixAuth module. Here's what my config looks like. The prefixes are associated with permanent endpoints. [Gatekeeper::Auth] PrefixAuth=sufficient;ARQ,LRQ default=deny [PrefixAuth] 123=allow ipv4:192.168.0.31| deny ipv4:0/0 180=allow ipv4:192.168.0.31| deny ipv4:0/0 233=allow ipv4:10.1.1.1 | deny ipv4:0/0 00=allow ipv4:192.168.0.31| deny ipv4:0/0 00=allow ipv4:192.168.0.56| deny ipv4:0/0 233=allow ipv4:192.168.0.24| deny ipv4:0/0 ALL=deny ipv4:0/0 The problem I'm having is, eventhough I'm allowing a few IPs to make calls to the above prefixes, any end point could make the call to these prefixes. So how do I specify that unregistered endpoints can only dial a particular prefix based on their IP address. regards, Zak __________________________________________________________________ Introducing the New Netscape Internet Service.
