The following works fine with me (using kernel 2.6.14.2):
Setup:

Internet <---> router <---> bridge <---> laptop

I want to DNAT pings to IP address 195.130.131.7 (google) to my router
(192.168.0.1). The bridge has no IP address.

#brctl addbr br0
#brctl addif br0 eth0
#brctl addif br0 eth1
#ifconfig br0 0.0.0.0
#ifconfig eth0 0.0.0.0
#ifconfig eth0 0.0.0.0
#route add -net 0.0.0.0 netmask 0.0.0.0 dev br0
#echo 1 > /proc/sys/net/ipv4/ip_forward
#iptables -t nat -A PREROUTING -d 195.130.131.7 -j DNAT \
--to-destination 192.168.0.1

Something similar should work for you. If it doesn't then give a clear
description of what rules you are using, what is happening to the
packets and what you think should be happening.

cheers,
Bart
