Hello,

can anybody please spot an error here?

# sudo service iptables start
Flushing firewall rules:                                   [  OK  ]
Setting chains to policy ACCEPT: filter                    [  OK  ]
Unloading iptables modules:                                [  OK  ]
Applying iptables firewall rules: iptables-restore: line 20 failed
                                                           [FAILED]

And my /etc/sysconfig/iptables is (I'm trying to enable
Samba, Apache, FMS dev. ed. and throttled SSH at 22 and 443):

*filter

COMMIT

Any hints on how to debug those issues?
The error message line points to the COMMIT.

Thank you
Alex
