Hy!

Im confused about what our elster-Software wants but, well, her it is how far i understand the problem.


I would have to install a server that would listen to some ports. lets say:

10000
10001
10002
10003

When the elster client is sending data to the port 10000 it should be routed to the ip xx.xx.xx.xx
When the elster client is sending data to the port 10001 it should be routed to the ip yy.yy.yy.yy

So this would be what it should look like


'Proxy'-Ports Internet

Elster --> 10000 --- > xx.xx.xx.xx
Client --> 10001 --- > yy.yy.yy.yy
--> 1000n --- > zz.zz.zz.zz

How would i do that ? with Port-Forwarding an my SuSELinux Firewall ???

Thanks for your ideas!

you could do some portforwarding in your firewall
what firewall do you have if any?

SuSEFirewall 2

it wolks....

iptables -t nat -A PREROUTING --dst xx.xx.xx.xx -p tcp --dport 10000 -j DNAT --to-destination 62.xx.xxxx:8000
