hi!
i´m almost ashamed to ask such a beginner question, plz no flaming ,but i just don´t get it to work.
can anyone give me a little tut for a simple an easy portforwarding?
there are several things i don´t know/understand:
when i try to forward a port, e.g. 1000 to a client on my internal lan, i have to set up a pekt filter rule and a dnat rule.
so, i create a servicedefinition, called testservice with value 1000 for tcp (or udp, not important here).
then i create a paket filter rule that allows traffic from, and then i run into problems: from where? from "any" or from "external(adress)" or "external(network)". which is the right setting for connections from the "entire big bad internet"?
and i think my bigger problems are with dnat/snat.
dnat is destination nat, and changes the destination adress from a packet. so, my external ip gets a packet that should be forwarded to an internal machine, the dest ip is changed from 213.xxx.xxx.xxx to 10.100.1.5
when i do this, is there anything i have to change else?
i hope i could describe my problem somehow understandable, my english in such things leads to be bad.
thanks in advance
