Redhat PPPoE Frequnce Disconnect

[imcslee]

I have setup my Redhat 8.0 as a router to use to share the internet connection to all my client.But after a few minute of idle my connection seem like autodisconnected.While I try to reconnect again I can't make it.I have a call my ISP to delete my previuos login session then only I can connect to internet again. Is anyone have this problem occur also?Please give me some usefully advise to solve this problem.This problem already border me for quite sometime.

Note : I'm using (DSL) with PPPoE protocol to connect to internet.
