From Bugzilla Helper: User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.4.0-0.26 i686) Using kernel-2.4.0-0.26 (from preview packages in RH7.0 CD), the ipt_MASQUERADE module incorrectly needs ipchains module to be loaded. As a result, when trying "modprobe ipt_MASQUERADE", the system tryies to insmod ipchains, but fails because iptables is already loaded. I found the dependency in modules.dep file. Reproducible: Always Steps to Reproduce: 1. lsmod will not show neither iptalbes or ipchains modules loaded. 2. If trying to 'modprobe ipt_MASQUERADE' I got unresolved symbol "ip_nat_setup_info". 3. If I 'modprobe iptable_nat' first, this symbol will be available. 4. Then I 'modprobe ipt_MASQUERADE' and got "failed to insmod ipchains", because iptables is already loaded. 5. A workaround it to simply "insmod ipt_MASQUERADE" after "modprobe iptable_nat".
This should be fixed in rawhide.
