Subject: Weird ARP behavior with DSL
Content-Type: text/plain; charset=us-ascii

I have a redhat 5.1 box and I have two ether net cards.

The second card is pointing to a DSL bridge (modem).

The ISP is messed up, so they pointed 12 static IPs at me.

I am attempting to use arp to route IP traffic inside.

Currently if I ifconfig eth1:1 xxx.yyy.zzz.99,
it works fine.

but if I  arp -i eth1 -Ds xxx.yyy.zzz.98 eth1 pub

I get nowhere.  .98 is eth0 in this case, but nothing helps (even using
other value on Network 0).

I am posting to this group since this is a different setup.

It is 

   Box A [network0]  Box B  [network1]  DSL Modem [DSL] Router
            
The DSL modem is running bridge mode.  I assume arping will be bridged
(especially since aliases work).

I've made this same scenario work with a RadioLAN. Am I being goofy, or
is DSL and arp not working?

also arp keeps saying "eth0"

 arp -an
? (xxx.yyy.zzz.104) at 00:40:05:14:D1:5F [ether] on eth0
? (xxx.yyy.zzz.254) at 00:10:67:00:13:62 [ether] on eth1
? (xxx.yyy.zzz.98) at 00:20:AF:30:DA:5F [ether] PERM PUP on eth0
? (xxx.yyy.zzz.100) at 00:20:AF:30:DA:5F [ether] PERM PUP on eth0
? (xxx.yyy.zzz.97) at 00:20:AF:30:DA:5F [ether] PERM PUP on eth0

[root at eater net-tools-1.33]# cat /proc/net/arp

xxx.yyy.zzz.97     0x1         0xe         00:20:AF:30:DA:5F     *
 eth0

is this part of the problem?

Thanks!
