Don't forward to the modem; set Bind up as a caching nameserver as per 
the docs and make sure that /etc/resolv.conf has as first entry 
"nameserver 127.0.0.1" and as second "nameserver ip.of.your.modem".

If you get a private address from tour modem's dhcp server, edit 
/etc/rc.local something like:

sed -i s/192.168.1.254/127.0.0.1/ /etc/resolv.conf
echo "nameserver 192.168.1.254" >> /etc/resolv.conf

otherwise, every time you reboot your PC you'll get the modem as nameserver.

I have just this setup on this FC6 machine, with a Thomson speedtouch 
ADSL router.

Best,
