Yes, I think that will fix your problem.

When you compile and install iptables, pay attention that the default 
installation will be in /usr/local/sbin, whereas RH defaults their 
installation to /sbin. 

For this reason, don't forget to uninstall iptables-1.2.5 (rpm -e iptables), 
or you will still be running "/sbin/iptables" (the old version). instead of 
"/usr/local/sbin/iptables" (the new version).

You may also compile iptables-1.2.7a to install in /sbin of course (see 
Makefile).

In case of doubt, run "whereis -b iptables" to get a list of all 
iptables-binaries in your system..
