Thanks Eric, We run a 2811 Cisco core router that feeds a Vyatta server for handing out private static and public addresses which runs into a Mikrotik bandwidth unit then over six backhauls to various towers from our head end. Six towers relay to the next tower down. We have about 70 Public IP addresses that go to various locations but a majority are in the 10.80 type of addressing.
Does anyone know when you put the filter for icmp in a Mikrotik router Firewall under action do you "accept" or "drop" under action and then "forward" under the chain? Thanks for your help its day 2 and I have 35 devices down, wait now it's 19, wait now it's 44, I hate this!
