[Luis Miguel Cruz Miranda]

I execute this line:

# iptables -t nat -A POSTROUTING -s 10.1.0.253 -o eth0 -j SNAT --to-source 
194.149.216.62
iptables: Invalid argument

but it returns Invalid argument????

Did you use this as is ...with a broken line. I tried your syntax in one
line and got no errors.

Try using it in one line....

No there is no broken line at all, the borken line is beacuse of the eudora 
mail client, sorry.
I search into google and the news at google without find the solution.

I am using redhat 7.3, kernel 2.4.20 patched with 
patch-o-matic-20030218.tar, iptables is iptables-1.2.5-3 from the official rpm.

Is there any incompatibility between the patched kernel I have and the 
iptables rpm?
Should I recompile the userspace programs?

Yes I think this is your problem. Just get iptables v1.2.7a source code 
(or the latest CVS)
and compile it again. Everything should work fine after that.

Luis,

I have seen similar problems when iptables has not been compiled and
installed
correctly (The INSTALL files needs to be read carefully).  If your syntax is
correct
are you are running 1.2.7a on a linux system, are you booting the right
kernel that
you used to build iptables?  Some times this problem also happends because
the
target module has not been loaded from the library or the kernel.

Good luck,

Jose.
