I need to move a PPP link from a pair of modems to a wireless network.
The wireless network has MAC layer bridges with Ethernet ports, so
basically what I need to do is reconfigure the client (running FreeBSD
3.2 with security patches and userland PPP) and the server (also running
FreeBSD 3.2 with security patches, but with kernel PPP) to communicate
via PPPoE rather than via the modems.
I've checked out the FreeBSD Handbook and have found a brief explanation
of how to set up a client running userland PPP for PPPoE. However,
there's no mention of what to do on the server side or with kernel PPP.
Finally, while I'm not intimately familiar with PPPoE, it's obvious that
it cannot use IP addresses for its underlying communication; it must use
MAC addresses and have its own DLC mechanism. This suggests that its
packets probably have a unique Ethertype. Does anyone know offhand what
that type is, so that we can instruct the bridges to allow it through?
(Currently, the bridges only allow TCP, UDP, ICMP, and ARP and block
types such as IPX.)
Pointers to information on any of these things, and/or sample
configuration files, would be MUCHLY appreciated.
