Re: pppoa connection

I do have a fixed IP address. I have tried using their modem
as a router and assigned my IP address to the modem. This forces
me to use the NAT facility in the modem and it keeps dropping
my ssh sessions. I have also seen the modem drop the pppoa
connection and not be able to reestablish it until I reboot the
modem.

The only thing this fine piece of equipment has been able to do
reliably is maintain the virtual circuit to the ISP. Anything
at a higher level in the protocol stack is too flakey. Hence,
I just want it to act as the most stupid of pipes between me
and the ISP.

Other people successfully use this modem to connect to their ISP
when the ISP accepts pppoe connections and the modem is configured
as a bridge. Unfortunately, my ISP doesn't support pppoe, only
pppoa.

So, can I pull this off?

Try just treating the modem's ethernet as though it were a local
router port, using (unless they've assigned you a fixed address)
DHCP. If your ISP is like mine, the PPPOA and 1483 stuff is
between the modem and their router and invisible to you.

I am wondering if the following is possible.

My local ISP only uses pppoa for their DSL customers. They
have provided me with an Actiontec GT701 DSL modem. I want
to configure the modem to use RFC 1483 transparent bridging.
This modem has both an ethernet and USB interface for the
LAN connection.

I have a FreeBSD box that I have configured as my router and
firewall. It is currently being used to connect to my ISP
using a radio link so I know that it is configured properly
for routing and firewalling.

The question is, can I establish a pppoa connection from the
FreeBSD box to my ISP by sending packets over ethernet to the
DSL modem?

Thanks,
Kim
