Gateway inherits virtual interface instead of physical interface

Hi, all. We're running pfsense 2.0.1-RELEASE (i386) and all was working fine for a few weeks when we suddenly encountered a routing problem with our default gateway interface:
Destination Gateway Flags Refs Use Netif Expire
default xx.xx.76.129 UGS 0 2469196 vip17
10.0.0.0/8 10.11.41.1 UGS 0 1904384 em4
xx.xx.76.145 link#25 UH 0 0 vip17
It took us a while to notice that the default gateway xx.xx.76.129 (Internet facing) has "vip17" interface, owned by another host, xx.xx.76.145. It's interface should be "em3", the physical interface connected to the ISP switch.
Any ideas on how to force our default gateway to use the em3 interface? After several hours of Googling and failed troubleshooting, we finally decided to restart/reboot the 2 boxes but problem persisted for both.
Appreciate the help. Thanks.
