I am sending udp packets through ppp400, and I see them appear on ppp401

The thing that is bothering me is that all I see on rddVR4 (172.1.2.1)
is arps for 172.1.2.2, but the 'tell' IP is that of the
originating ppp400 link, not the IP of rddVR4, as I expected:
21:47:16.119640 arp who-has 172.1.2.2 tell 11.1.1.3
21:47:17.119371 arp who-has 172.1.2.2 tell 11.1.1.3
21:47:18.119254 arp who-has 172.1.2.2 tell 11.1.1.3
21:47:19.273118 arp who-has 172.1.2.2 tell 11.1.1.3
Unless I'm missing something dumb, a similar setup with all ethernet-ish
network devices
works fine.
I have also enabled arp filtering:
# Only answer ARPs if it is for the IP on our own interface.
echo 2 > /proc/sys/net/ipv4/conf/all/arp_ignore
and for every device used in these routing tables:
echo 1 > /proc/sys/net/ipv4/conf/[dev]/arp_filter
Any idea what I need to do in order to make the source IP for the ARP
packet correct?
Wouldn't that be controlled by arp_announce?
Yes, after trawling through the code I found that one, and setting it to '2'
seems to have fixed everything.
Thanks,
Ben
