Hi all- (Is this list working right? - I'm getting lots of wierd stuff in the digests...but anyway...) Other attempts to find the answer to this have failed, hopefully this isn't too off-topic. We have several subnets connected via Frame Relay. Call them 10.10.1, 10.10.2, 10.10.3, etc. On each, the gateway is the 254 address, e.g., 10.10.1.254. Sitting at a 10.10.1.n machine, I can ping the gateway 10.10.x.254 on every subnet. However, a ping to the broadcast address as ping -c1 10.10.x.255 fails on some of the subnets (from outside that subnet). From within the subnet, the ping to the broadcast succeeds everywhere. Pings to known hosts (and 10.10.x.254) succeed always from everywhere. So, my question is, why would I be able to successfully ping to the broadcast address from within a subnet but not from outside the subnet, but only in certain cases? We have a mix of windows, FreeBSD, router, and other machines on each subnet. (I'm led to ask all this since where the broadcast doesn't work from outside the subnet, neither does DHCP, which is proving to be a real problem!)
