Freebsd 10, ip4:

router1 192.168.1.20/24 carp master vhid 192.168.1.1 router 2 192.168.1.21 CARP VHID backup 192.168.1.1 named running on 192.168.1.100, another named on 192.168.1.101 pen -U 53 192.168.1.100:53 192.168.1.101:53
on router 2 will transmit packets with source address 192.168.1.1 -- causing all replies to packets sent by pen on router to go instead to router 1.

Option added to select local address for upstream connections. The command lines would be something like

pen -U -O "source 192.168.1.20" 53 192.168.1.100 192.168.1.101

and

pen -U -O "source 192.168.1.21" 53 192.168.1.100 192.168.1.101

This is in latest Git. Please try it out and if it works out it goes into the next release.
