XG Can't ping ISP gateway but users can

We have an XG 310 that has two separate internet connections to the same ISP for redundancy and load balancing.  Obviously, these two connections are set up on their own WAN ports on the XG, each with a different static IP (and each port has a different MAC address).  The issue is that the second connection shows down, however, it will pass internet traffic that is forced out that port with the EXCEPTION of ping.  For whatever reason, the XG cannot ping anything ping-able on the internet.... HOWEVER, clients on the LAN that are forced out that port can ping hosts on the internet.  We also have a third internet connection to a different ISP for backup/failover that is working just fine.  Does anyone have any input as to why the XG is acting this way?
