I recently had the *exact* problem with some 4.3-REL machines. In my case, it turned out that the telco had upgraded some equipment that caused the problem. Could it be possible that something in the PPP or PPPoE implementations makes FreeBSD prone to problems in certain fringe situations? -- Matthew Emmerton || matt@gsicomp.on.ca GSI Computer Services || http://www.gsicomp.on.ca On Sat, 1 Dec 2001, Greg Lane wrote: > G'day all, > > Somewhere between 4.3-RELEASE and 4.4-RELEASE something has changed > which makes my PPPoE connection to Telstra ADSL (Australia) not work > anymore.
