Mandrake ignoring Shorewall?

I'm a little confused.
My network was running OK for internet sharing. Then I upgraded my kernel to 2.6.7 and now it doesn't work. My Shorewall ruleset is pretty simple allowing tcp 20,21,22,80 to go through... It was working alright with the other ports closed.... BUT NOW.. my nmap shows

21/tcp open ftp
22/tcp open ssh
53/tcp open domain
80/tcp open http
111/tcp open rpcbind
139/tcp open netbios-ssn
443/tcp open https
445/tcp open microsoft-ds
3128/tcp open squid-http
6000/tcp open X11

( I know I shouldn't pubish)...
Computers behind my firewall are getting their IPs fine via dhcpd. Why would Mandrake ignore shorewall. PS: I have a list of my modules before and after the upgrade.. the ones missing from the new lsmod:
md5, supermount, ipt_multiport, udf, nls_iso8859-1, hid

Can it be a kernel problem (cause that's what I've done) or a config prob (cause now it ignores my shorewall rules)...

any help is appreciated

since shorewall is based upon iptables, and i assume that you have iptables installed properly (since it worked before the kernel update), you probably havent built netfilter capabilities into your kernel, check this path within your kernel config (make menuconfig, its the same using the gui)

Device Drivers -> Networking support -> Networking options -> Network Packet Filtering (should me selected) -> IP: Netfilter configuration -> here you can select what you need, if you don't know what to select, simply select all, you basically need the "IP tables support" and the stuff below...
