Recently our company has purchased a new ethernet capable time clock system. I've read the manual concering the time clock software and tested in a lab environment using a laptop and small switch, which works fine. However, upon real implementation, I am having some issues having the software see the clock over the WAN. Obviously the only variable here is the WAN. I have two Cisco 2621 routers running IOS 12.0 at each site connected via a T1. We are not doing any type of blocking as this is a point to point connection. I contacted the time clock tech support and they informed me the reason the software would not see the time clock over the WAN was a networking infrastructre issue as by default UDP broadcast are disabled over a WAN link. The manual states "The WAN must allow for UDP broadcasts (via
255.255.255.255) on Port 30718, and TCP/IP on Port 10001. How would I go about allowing UDP broadcase (via 255.255.255.255) across the WAN? That seems kinda crazy to me to even do that as it creates massive traffic but I have to do it initially to get the software to see the clock. Any help would be greatly appreciated.
