IPTABLES FORWARDING won't work

IPTABLES FORWARDING won't work

[Jerry Alexander]

Dear NF:

         Sent the earlier message and so far no help
         Some additional info.   It is a linux 2.4.20-8.
         iptables-save  shows ":FORWARD ACCEPT [0:0]"
   which means no packets/bytes have been forwarded.
         No error messages from /var/log/messages.
         Other than loading the modules,  echo'ing a 1 into ip_forward,
and putting in a FORWARD rule I don't think there is anything else to do.
          I did  go into System Settings and set it to "no firewall".
          Any help?!

                                                                     Jerry

example entries:

-A FORWARD -d  192.168.0.17 -p udp -m udp --dport 32779 -j ACCEPT

....

           
Dear NF:

          Had FORWARD"ing working a couple of weeks ago.
          Other than loading the modules,  echo'ing "1" to ip_forward
and entering a "iptables -A FORWARD ...."   it worked fine.
          Ran "ping" and  "iperf" and captured the packets on ethereal and
could see the additional packets.
          Have tried  with a kernel with everything built in and a kernel
where I loaded the modules.
           It worked with no hassles when I tried it before and now
for the life of me, can't figure out why it just doesn't work.
          What is strange is that  setting "-t nat -A PREROUTING" and
changing the destination address works fine!
           Not sure what else to try since it doesn't take much to get
it working(when it works!).
          Appreciate the help.

                                                    thanks,
                                                           Jerry
