[nmglug] proxy arping,

[Andres Paglayan]

Hi,

does anybody knows how to properly set proxy arping?

I have a router with 192.168.1.0 in one side and 192.168.50.0 in the  
other,
at the 50.0 side, I am routing traffic to other subnets as well, ie  
172.16.2.0/23

For the applications we are running, instead of regular natting,
I have to use NETMAP target of iptables,

which instead of making the packets as going out from 192.168.50.1
they are mapped to addresses at 50.0/24
i.e. when packet goes from 192.168.1.5 to 172.16.2.34 trasversing the  
192.168.50.1 device
the router mangles it an makes it appear as going out from 192.168.50.5

everything goes fabulous, but I am having a problem with arping,
arp questions addressed to 192.168.50.0/24 are not reaching my  
routers device,

I have been reading and experimenting with this a bunch,
echo 1 > /proc/sys/net/ipv4/conf/eth2/proxy_arp
on the proper device is set, but still not proxy arping,

is there anybody with experience on this?

Thanks,

Andres
