Watchguard firewall causing migrationwiz migration to office 365 from SBS 2011 standard to fail?z

I am doing my first sbs 2011 Standard to office 365 hosted exchange migration.

I am using migration wiz and 4 of 5 mailboxes failed. one talked of actively refiusing the connection.

It reminded me - there's a watchguard firewall at the sbs 2011 location.  I remember once someone else having a problem with too much data going to /. from 1 place that the watchguard shut it off - there's a setting to limit amount of data to / from 1 external location that was on by default.

Anyone know where that is?  Could that be why they are failing the migration?

can you tell me where to look to disable that if it's on. and maybe where to look to see if that feature was activatted in the last 48 hours?

THANKS!
