I have some investigative research to do into PPPoE and a wireless modem device. I'm have been using rp-pppoe by Roaring Penguin to start a pppoe session as a client. Whilst watching packets being sent by said program (using wireshark), I have noticed that there is no difference when the -s (synchronous mode) option is set or not.
I configured cisco router as pppoe server and my clients are PC's, the problem is NAT working so the client cannot ping other routers i had to static route the client pool on these router,
any ideas for best NAT setup?
