modifying /etc/sysconfig/iptables manually, but with no success

Hello,
I setup a RHAS3 with 2 NICs, one connected to internet with real IP
and the other connected to my local LAN. I have modified the
ip_forwarding file content and issued the iptables line below

iptables -t nat -A -POSTROUTING -s internal.ip/internal.mask -o ethx
-j SNAT --to-source external.ip

which allowed my to allow my local users use this box as a gateway to
internet.

For setting up a web server locally, and by assigning another real IP
and making proper forwarding so that this server would server both
local and non-local internet users, I added the line

ifconfig eth0:7 real.ip.no.7 netmask 255.255.255.0

into /etc/rc.local and also issued the following lines at the command
prompt ;

iptables -t nat -A PREROUTING -d real.ip.no.7 -j DNAT--to 10.0.0.7
iptables -t nat -A POSTROUTING -s 10.0.0.7 -j SNAT--to real.ip.no.7

and it work. People would access this server both from inside and
outside with apropriate IP numbers.

This way I figured out that the /etc/sysconfig/iptables file included

So I though it would be fine modifiying this /etc/sysconfig/iptables
file manually to add the iptable definitions of all my other 20+
servers. So together with

-A PREROUTING -d real.ip.no.7 -j DNAT --to-destination 10.0.0.7
-A POSTROUTING -s 10.0.0.7 -j SNAT --to-source real.ip.no.7

I added the lines ;

-A PREROUTING -d real.ip.no.8 -j DNAT --to-destination 10.0.0.8
.......
-A PREROUTING -d real.ip.no.49 -j DNAT --to-destination 10.0.0.49

and also

-A POSTROUTING -s 10.0.0.8 -j SNAT --to-source real.ip.no.8
......
-A POSTROUTING -s 10.0.0.49 -j SNAT --to-source real.ip.no.49


Unfortunately my gateway Linux now forwards the traffic of only the
server 10.0.0.7 and no one else.

the current iptables-save and ifconfig results are below and I cannot
find out what have I done wrong.

Any help is appreciated.

Regards.

The most simplest way to fix this is to go back to the original iptables
file that was working before you played with it and then go through the
steps you did before to see it working properly After it is working
the way you want issue an 'iptables save' to save a new iptables file
in /etc/sysconfig. Then look at it and you will see what you did wrong.
