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” It looks like all your problems actually comes from the $EXTIP variable. check the beginning of the script if it is initialised. I guess is the External IP address. It might be just assigned like EXTIP="xxxx" or your script might try to get it from the interface. If your script pools it from the interface, then that part might be stuffed. The common issue with some major releasese is the new rules of naming interfaces. make sure that EXTIF wasn't changed. Running the script with "bash -x script_name" will show you that $EXTIP is blank

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!
