[Mikrotik] Connection pauses?

  Don't know.  This is a remote POP, and there are 3 backhaul hops going 
from our NOC to this POP.  When I put all the parts together, I had 
(apparently) forgotten to D/L the configuration, so I had to MAC telnet 
into it in order to load the config.  That did work though.

Read also my post about the outbound ping.  If that's running, the 
pauses are less frequent, and much shorter.
