Hi everybody, It appears that the netfilter_mangle module is required for nat to work properly. I would like to thank Redhat for their very nice rc.firewall-2.4-stronger script. It works mostly - just this teenie little problem with it... Port forwarding now finally works and I can play Nectarine Radio on my laptop with a decent set of rules in the firewall. So, now I can try the government Java applet port forwarding problem and if I can get that to work somehow, then I can finally fix my client's machine. Thanks to everybody who read my desperate pleas and offered suggestions. Ten past eight pm and time for a cocktail to celebrate... Cheers, -- Herman Oosthuysen B.Eng(E), MIEEE Aerospace Software Ltd.
