I'm working with LEAF boxes as gateway machines. I'm trying to implement
Proxy-ARP to build a bandwidth manager for my network. I've gone as per
the lartc howto to implement a transparent bridge in an existing network
and plan to put in my tc script after this. I'm configuring the box as a
standalone one before plugging it into the network. I'm getting an error
when I try to delete a route for local LAN addresses thro' the external
interface in order to put in a specific one to route only packets meant
for the router's interface thro' that ethernet interface on the LEAF
box. The kernel version is 2.4.18 patched with htb and ipsec. Iproute2
is also installed.
My intended network goes as below. I put up a LEAF box to try this. LAN
Config is as under
10.0.1.1
Internet +-----------------+ eth0+-----------+eth1 |
===========> | Router/ VPN Box |----------|LEAF Bering|----------| LAN
Leased +-----------------+ 10.0.1.4+-----------+10.0.1.4 |
10.0.1.x
I set up interfaces file and checked all the settings. I'm unable to
delete the route for eth0 for 10.0.1.x addresses. I'm giving below the
transcript. I'm not able to figure out what the problem is. Can you help
me put this up please?

Since I'm going to be introducing this bridge into a production LAN, I'd
like this to work first shot. Any pointers please.
TIA
