Frontier dallas area ESP issues?

["Randy (K6RP)" <amps () djlab com>]

Hi all, 

Anyone from Frontier lurking or Frontier customers with similar issues? 
 We have a mutual customer in the Dallas area who is experiencing severe
dropping/limiting of inbound ESP packets, rendering their IPsec tunnels
for the most part useless since a few days ago.   Outbound packets make
it to their destination, the return packets do not.  On or off list is
OK.
