iptables NAT - what am I doing wrong?

I have two computers:

dual-boot win2003 and gentoo. IP - 192.168.1.1
win98. IP - 192.168.1.2

the win2003 has winroute firewall working and the win98 is able to surf the net using NAT and forwarded DNS.
the gentoo was configured by this outline:

compile the kernel modules related to netfilter, iptables.
emerge iptables
emerge firehol
emerge dnsmasq
rc-update add dnsmasq default
rc-update add firehol default

I configured firehol according to this tutorial (scroll to the buttom), modifying "195.97.5.192/28" to "192.168.1.0/24" and "ppp+" to "eth1".

Now when I boot the gentoo, the firewall is working fine, blocking connection attempts as expected. But the win98 is not able to surf the net.
I also tried a script generated from http://easyfwgen.morizot.net/gen/ with no success.
Can you see the problem here?

Can you ping the gentoo box from the win98 box? If yes then you probably just need to get the proper dns servers into the win98 dns.
1. Find out the dns from the gentoo box
cat /etc/resolv.conf

2. write down the two ip addresses it should show
then write them into the win98 network settings under TCP/IP Networking, restart as I think you have to.
