I'm not sure if this is the right place to ask this, (sorry). I looked at
the list archives and found some mention of ppp not being supported, but
perhaps something is possible.
The setup is like this:
1) [Computer]
| 172.16.0.30
| (via 100baseT ethernet)
| 172.16.0.31
2) [DSL daughter board in computer]
| 10.10.10.2
|
| (via DSL ppp link)
|
| 10.10.10.1
3) [DSL server]
| 192.168.0.50
| (via ethernet)
| 192.168.0.*
4) {LAN/gateway to internet, etc}
Currently node #1 and #2 have IP addresses on their own subnet. #2 has an
ip address for its end of the PPP link also. I want node #2 not only have
its IP address associated with the ppp link. So packets coming from its
ethernet port get relayed directly over the ppp link without any change, and
packets arriving from the ppp link get sent to the ethernet port without any
change. The daughter board is running linux, and its ppp link is brought up,
then it is assigned an ip address for its ethernet port. I want to avoid that,
so its ethernet port is transparent.
I was wondering if it was possible to bridge the ppp and the ethernet on
node #2 together, after the ppp link is established. So the new bridge would
have the ip address of that end of the ppp link (10.10.10.2). I don't want
there to be the 172.16.0.31 ip address assigned to the daughter board.
If this isn't possible with bridging, perhaps there is some other way to
do it with packet forwarding? But it would have to be forwarding at an
ethernet level I think.
I can't change the link between #2 and #3, but I can run whatever I want on
nodes #1 and #2 since they're running linux.
Thanks for your thoughts! Please cc me on all responses.
