Most of my network uses RB750 MikroTiks and I have no problem managing all my devices on the LAN. Recently we have had to upgrade a few of the RB750s to RB2011UAS for a bit more processing power (running a lot of mangle rules and queues...). One of the RB2011UAS works fine, but the rest of them will not allow ping or telnet to Alvarion VL devices but can ping UBNT devices just fine.

I have compared as many settings as I can between the unit that works and those that are not working and cannot find the setting I am missing. They are all running v5.20 and I cannot find any differences between the units. Hopefully someone has run into something like this and can point me in the right direction?
