So, my network layout is something like this:<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>[ freeradius ]<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>-- [ external* mysql ]<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>-- [ external* postgresql ]<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US>* external I mean as the databases are running in separate hardware but in the same physical network<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US> My customers are authenticating over PPPoE interfaces on two parallel servers that work as a backup for each other but they are running simultaneously.
