In a test scenario, i'm trying to set up a dialin router, to accept calls from a POS creditcard terminal, that is unable to perform any kind of authentication, but requires PPP and need's to receive an IP address trhough DHCP.
This seems to work according to plan( and looking at debugs), the problem is that no communication is established between POS and host on LAN behind router, please see snip of debug below.
Is this at all possible to get working?
*Mar 1 05:00:19.435: BR0:2 IPCP: Pool returned 192.168.101.14
*Mar 1 05:00:19.435: BR0:2 IPCP: O CONFREJ [ACKrcvd] id 1 len 10
Your output indicates that IPCP negotiation was successful and an IP address was assigned, was accepted, and was installed in the routing table. Yet when the router attempts to send to that address there is "encapsulation failure" which indicates that there is some piece of information that the router needs to complete the packet that it does not have. It would be helpful to know what ppp parameters you configured, and how you configured the dialer interface and the bri interface.
