I am just wondering if anyone has seen duplicate ping in Linux? I investigated a little bit and found that i get duplicate ping only from the DMZ range where the Linux box is and to one other specific range on across the VPN. I made sure that all interfaces on routers and firewalls have correct ip addressing and they do not have a broadcast IP. Any ideas are welcome. I also checked routing and everything is routed as it should be? Where could a problem be?
Sounds like the VPN configuration could be pooched. Be sure you aren't pinging the broadcast ip of the range across the VPN.
And what do you mean byQuote:

This only happens on Linux. As soon as i NAT the machine in to come from 10.84.1.2/27 it looks good. So there seems to be a problem with dmz and 10.84.48.0/24. Weird but routing is 100%, between the two initially i thought there was a loop somewhere. Any ideas?
