You can hardwire the ARP entry of your redirector to your Router. In that case
the router will not ask the shared media about the Owner of the IP.

why dont u use -arp as you can read it in the manual and as i written in my
post. I dont see a reason why it should not work.

Actually:


calista:/home/ecki# tcpdump -n -e -i eth0 arp &
[1] 26211
calista:/home/ecki# ping 10.0.0.7
PING 10.0.0.7 (10.0.0.7) from 10.0.0.3 : 56(84) bytes of data.
05:05:23.678782 0:0:c0:78:72:df ff:ff:ff:ff:ff:ff 0806 42: arp who-has 10.0.0.7 tell 10.0.0.3

--- 10.0.0.7 ping statistics ---

calista:/home/ecki# 05:05:25.670215 0:0:c0:78:72:df ff:ff:ff:ff:ff:ff 0806 42: arp who-has 10.0.0.7 tell 10.0.0.3

calista:/home/ecki# ifconfig eth0 -arp
calista:/home/ecki# 
calista:/home/ecki# ping 10.0.0.9
PING 10.0.0.9 (10.0.0.9) from 10.0.0.3 : 56(84) bytes of data.

--- 10.0.0.9 ping statistics ---
1 packets transmitted, 0 packets received, 100% packet loss
calista:/home/ecki# 

as you can see after using -arp my kernel will no longer issue 3 arp requests
for (not existing in my case) hosts.

And i do habe 2.4.0 with 3com ethernet.

Greetings
Bernd
