Hello Guilherme,
I find it interesting that when you ping to 172.24.18.4 the following
address appears:
Sending 5, 100-byte ICMP Echos to 206.24.18.4, timeout is 2 seconds:
Why is it sending to 206.24.18.4?
Sincerely,

yes, that's what I thought too, but proxy-arp is disabled..
interface FastEthernet0/1
ip address 172.24.18.5 255.255.255.252
no ip proxy-arp
rate-limit input access-group 170 296000 62500 62500 conform-action
transmit
exceed-action drop
duplex auto
speed auto
Thanks, anyway.

So your question is why there's a reply to such request....
My understanding is because of the proxy arp hehaviour of the router
that
will try to respond to an arp request on behalf of that 172.24.18.4
host....
So my suggestion to help u investigate this issue try to turn proxy arp
off
at the routers and see what happens with the protocol analyzer and pls
let
us know what happened....
But anyway that is my guess sure somebody at the group can help calrify
this
issue much better than me....
