Hello,
the following should be possible with IPIP tunneling (and ProxyARP),
I think. I'm afraid I wasn't able to get it done with Linux 1.3.22/23
on both sides (and net-tools-1.3.6 BETA3). Maybe I just fundamentally
misuderstood something.. or there are still some bugs :)
I would be very glad if someone who knows could tell me how it should
be done.
Ok, here it goes..
+---Ethernet/FDDI--------+

at other times (dynamic client address
static PPP with A.B.N2.x, e.g.)
reserved address !
A.B.N1.120 !
! ======== !
+----->// |client-ppp0-(A.B.N2.202)-!
========
Question: how to achieve, that even when using dynamic IP (ppp0 interface
has A.B.N2.x address) "client" is reachable as A.B.N1.120
and also using that address for outgoing packets?
As I said, I think I know how it should work (it doesn't though..),
but maybe I'm totally wrong..
Any help appreciated (even if this is not an important thing for me),
have a nice day,
Lutz
