About mangle table

["Panayiotis Gotsis" <pgotsis@btinternet.com>]

Hello from a newcomer and.. here I go!

The problem I face is something a search in the Internet did not solve,
neither does the documentation on www.netfilter.org

I am trying to use the command

iptables -t mangle -A PREROUTING -s <source_address> -j MARK --set-mark 1
/* the value is for the example, I try to use 2 or 3 also */

I am using iptables 1.2.6a.

The error I get is:

'ptables v1.2.6a: Bad MARK value `1
Try `iptables -h' or 'iptables --help' for more information.

I have seen a lot of tutorials using mark values of 1. Is it a problem with
the new version of Iptables? Am I doing something wrong? Or should I check
for some other problem in my configuration?

Thanks for the time
