Posted here as I assumed a lot of VoIP applications would be udp based.
Got a SMB client who uses a realtime app - they're in the transport industry. This app goes haywire periodically and costs them a lot of $. It has two parts a gateway PC that talks to their trucks and a dispatch pc that has a link to one of their biggest clients.
Gateway pc goes to one dsl line snapgear pro firewall/dlink 500 dls modem/router
Dispatch pc goes to another dls line linksys WRT54G (they're using that as a firewall only) and cisco 801 modem/router
Now unfortunately the two isps are related so an issue at one can take out both links. I'm moving one of the lines over to another ISP as fast as I can but its tricky coz its a 24/7 operation.
I was after at minimum a ping utility for udp. I've seen one on the web but can't find it.
The vendor is pointing the finger at the linksys saying its not dealing with the udp traffic. His explanation is that a firewall opens a port for udp traffic in this case 4240 and if traffic is going back and forth keeps it open. Some firewalls interpret this as an attack and keep closing the port.
So ideally I'm looking for something that will allow me to keep making logged udp connections through those lines.
The other thing I guess is just monitoring the status of the adsl connection. I could just run a ping -t to a logfile pointed at google. But I was hoping for something a little more sophisticated.
Much TIA all.

For your situation I would recomend that you use Cisco branded hardware or another brand designed for corporate use. The Linksys/Dlink etc... are fine for home use but are not always 100% reliable and may occasionally crash or need to be rebooted.
