The configuration files are the same of our FreeBSD 4.11 PPPoE server. But often we have two or more clients with different tunnels and the same ip address. The ip are dinamically distributed by PPPoE service. In the 4.11, I donīt have this problem, the server reject the connection if the client gave the same ip address of other client. >How-To-Repeat: set the same ip address in two different logins and then try to connect both...in 4.x series they cannot connect, but in the 5.x and 6.x series, they connect but none of them can ping to no one place. >Fix: I dontīknow how to fix this problem. I just know the 4.x series donīt have this bug. Iīm not a good C programming...rs >Release-Note: >Audit-Trail: >Unformatted:
