Hello everyone!
I have a problem trying to develop on shorewall some rules to redirect some
kind of traffic between two servers on Internet (both wit publics IPs).
I want to redirect all traffic with destination host A (82.xx.xx.xx) port
(xxxx) to host B (87.yy.yy.yy) port (xxxx).
I can´t do it with shorewall, or I couldn´t be able to do it.
Then I saw some iptables rules that do the job:
/sbin/iptables -t nat -A PREROUTING -p tcp -m tcp -d 82.xx.xx.xx --dport
xxxx -j DNAT --to-destination 87.yy.yy.yy
/sbin/iptables -t nat -A POSTROUTING -o eth0 -p tcp -m tcp -d 87.yy.yy.yy
--dport xxxx -j SNAT --to-source 82.xx.xx.xx
The problem is that I can´t put this rules on shorewall and this rules only
work if shorewall is stopped. If shorewall is running and y execute this
rules, the system doesn´t tell me anything, but don´t work. If I stop
shorewall and run this rules, works.
Any suggestion about how implement this issue?
Thanks a lot everybody!
