I am trying to configure a 837 router to connect to an ADSL circuit (PPPoA) with a PIX 515e behind it. I have been given a 5 public IP address to enable this.
I just want the 837 to provide ADSL connectivity, with all access (NATing, IP Sec etc) done through the PIX.
How do I configure the 837 to do this. I assume I have to use the IP unnumbered command.
