Your error seems to be obvious as you have the ipchains module running
.you can find this by
# /sbin/lsmod (and see for the lines ipchains)
so if you want to insert iptable modules as you had done(modprobe ip_tables). first
you have to unload the ipchain module. this can be done by
# /sbin/rmmod ipchains
and then run the command modprobe
# /sbin/modprobe ip_tables
and check this out by executing lsmod command.
also make sure that you do not enable both ipchains and iptables in the startup
runlevel.
you can check this out using
# ntsysv
and disable the ipchains if you are using iptables
# chkconfig --del ipchains
# chkconfig --list ipchains (it should show "off" in all run
levels)

yes redhat 7.3 still uses ipchains instead if iptables .so this error is
obvious
in certain cases.
