port forwarding with ipchains / firewallpackage suse 6.4

I have serious problems installing a working port forwarding setup on a
SuSE 6.4 box. I have a internal webserver I want to make public.

+------------+ +--------------------+
internet ---| myfirewall |----| internal www-server|
| 195.x.x.x. | | |
+------------+ +--------------------+

I've red all kind of masquerade, ipchains and firewall-howtos I could get
but it still doesn't work or said the other way round: I just don't get

I have no problem using the Internet from the internale network,
masquerading seems to work fine.

I'm using the /etc/rc.config.d/firewall.rc.config file with the parameters

FW_SERVICES_EXTERNAL_TCP="www ssh domain smtp"

but it doesn't work. I tried all other kind of combinations and also with
the option


but I can't make it work.

I installed ipmasqadm since I couldn't find it on the CD's and it was
mentioned in all the howto's


portfw -a -P tcp -L 195.x.x.x.x 80 -R 80

didn't change anything neither.

I'm using the standard 2.2.14 kernel which comes with SuSE 6.4, I
recompiled and made sure alle IP and firewall options found their way
into my kernel.

Any hints and help would be apprechiated very much. I can send you a
ipchains-save dump if this helps helping me...

Do I need to install anything that doesn't come automatically with the
suse firewall package?
