> How does one set proxy arp on a linux system ?
On which kernel version. Here is an example for 2.0.36
# proxy arp for individual machines
/sbin/arp -Ds 158.144.23.1 eth1 pub
/sbin/arp -Ds 158.144.23.2 eth1 pub
/sbin/arp -Ds 158.144.23.5 eth1 pub
# proxy arp for subnets
/sbin/arp -Ds 158.144.23.4 eth0 netmask 255.255.255.255 pub
/sbin/arp -Ds 158.144.23.64 eth0 netmask 255.255.255.192 pub
/sbin/arp -Ds 158.144.23.128 eth0 netmask 255.255.255.192 pub
/sbin/arp -Ds 158.144.23.192 eth0 netmask 255.255.255.192 pub
In 2.2.x you have to enable it with something like
echo 1 > /proc/sys/net/ipv4/eth0/proxy_arp
or similar, I do not remember.
