This really sounds like routing issues. Maybe subnet mask or sth. like that. I
think its time to follow Tom´s offer to give a Shorewall dump as described in
the troubleshooting phase on www.shorewall.net

Does x.x.214.101 represent your new ‚original destination’ in rules file?
If yes, this sounds like a hierarchy problem in your rules file where another
rule may applied before the one you want.
For example.
DNAT net dmz:192.168.0.7 tcp 80 -
x.x.214.101
DNAT net dmz:192.168.0.6 tcp 80 -
x.x.214.101
This would mean, that a http request to your original destination will always
apply the NAT to 192.168.0.7 because its more near to the top of the file.
Go to /etc/shorewall and do a ‘cat rules | grep 214.100’ if you see more than
one tcp 80 rule this could be your problem. If you do the same with 214.101 and
see only one tcp 80 rule you have your answer.

I just changed NAT IP to another NAT IP:
original: x.x.214.100 192.168.0.6
changed: x.x.214.101 192.168.0.6
Internet can access to web by x.x.214.101
What's this problem?
Thanks !

And you probably wanted
DNAT net dmz:192.168.0.1 tcp 80
But randomly changing the rules without understanding what the real
problem is seems unwise. Wilson doesn't even know if the problem has
anything to do with Shorewall.
I repeat my offer to look at the output of 'shorewall dump' but I must
do it in the next 30 minutes because the rest of my day is full with
meetings.
