Dear All,

I have a "iptables script file" which I copied from the net that work
for years, it stopped working yesterday after I upgrade from Ubuntu
16.04 to 16.10. I am a beginner so the only way for me to diagnose the
problem is to comment out line by line to see what cause the problems,
my finding as follows;

482 $IPTABLES -A INPUT -i $EXTIF -s $UNIVERSE -d $EXTIP -m state --state  \
483 ESTABLISHED,RELATED -j ACCEPT
error message;
Bad argument `state'

offending line;
527 $IPTABLES -A OUTPUT -o $INTIF -s $EXTIP -d $INTNET -j ACCEPT
error message;
Bad argument `192.168.0.0/24'

offending line;
542 $IPTABLES -A OUTPUT -o $EXTIF -s $EXTIP -d $UNIVERSE -j ACCEPT
error message;
Bad argument `0.0.0.0/0'

offending line;
592 $IPTABLES -t nat -A POSTROUTING -o $EXTIF -j SNAT --to $EXTIP
error message;
iptables v1.6.0: option "--to" requires an argument

Also, variables INTNET=”192.168.0.0/24” and UNIVERSE=”0.0.0.0/0”


I have searched the net for answers but most of them indicate
something like "miss typing" etc. However, as the file work fine up to
Ubuntu 16.04 (I have not touch the file in any way) so something must
have changed in 16.10 and I am out of ideas.

Thanks in advance for the assistance!

Best regards,

Victor Mong
