Sorry for extra traffic to the list.
I've only one machine 192.168.1.1 with ethernet card attached to it, but
with no other hosts in network 192.168.0.0/16. This machine is PPP
server which assigns IP address 192.168.10.1 for connected client and
tries to do proxyarp with no success. Here is some info I collected out
after the ppp connection has been established:

Then ping on both hosts has been run
ping 192.168.10.1 (from 192.168.1.1)
ping 192.168.1.1 (from 192.168.10.1)
Both of pings told nothing, but 100% packet loss.
Packets were also dumped by tcpdump on both machines.
tcpdump -n -i ppp0 on 192.168.1.1
02:11:31.477168 192.168.1.1 > 192.168.10.1: icmp: echo request (DF)
02:11:31.482446 192.168.10.1 > 192.168.1.1: icmp: echo request (DF)
02:11:31.482672 192.168.1.1 > 192.168.10.1: icmp: echo reply
There were no echo reply from 192.168.10.1 to 192.168.1.1
tcpdump running on eth0 and lo on 192.168.1.1 shows no packets.
tcpdump -n -i ppp0 on 192.168.10.1
02:39:33.552747 192.168.10.1 > 192.168.1.1: icmp: echo request (DF)
There were no echo reply from 192.168.1.1 to 192.168.10.1 :-(
Finally arp table on both hosts after ping:
arp -n on 192.168.1.1
192.168.10.1 * * MP eth0
arp -n on 192.168.10.1 shows nothing.
Manually running "arp -i eth0 -s 192.168.1.1 -D eth0" on 192.168.1.1 did
nothing, but appropriate record in arp cache of 192.168.1.1.
I'm not sure whether I really need proxyarp, but in manuals I've read
were pointed that it's the easiest way of getting working remote
network access in may case (I need only one client to access only my
computer).
And could anybody tell me what the hell with this 169.254.0.0/16
network? Nobody ever specified it anywhere on both hosts.
Thank you!
