SNAT rules

[Stefan83]

Hi,

I'm in the process of setting up Zentyal 3.0 in a small office environment (<15 users). I configured my server with 2 NICs - 1 internal (network: 10.0.0.x; server: 10.0.0.1), 1 external (connected to the internet router; network: 192.168.178.x; server: 192.168.178.43).

Clients in my internal network (10.0.0.x) can use all of the Zentyal services just fine. However, there is an old Windows XP machine in the external network (IP: 192.168.178.200) acting as file/database server I need to make available to the internal network - at least temporarily.

I already added a rule to the "Traffic from external networks to internal networks" section simply allowing all traffic. Now I can map shares or access the database from within the internal network. As I observed, all clients connect to the Windows XP machine using the external IP of the server (192.168.178.43). If more than one client connects, the Windows XP machine is "randomly" dropping connections (seems logical to me, because it can only see this one IP).

After a lot of searching and reading I think SNAT is what I need here. If I understand its principles correct, my internal clients would then use an individual IP on the XP machine (ie. 192.168.178.210; 192.168.178.211; ...) not mixing something up as it's doing now.

Is my assumption correct? What values I need for the SNAT section in Zentyal webinterface? Especially I'm confused what to enter in the "SNAT adress" field.

Any help would be appreciated.

Thanks,
Stefan

Hi,

isn't there anybody who can help me with this? Or maybe point me to a good documentation about SNAT rules in Zentyal?

Thanks,
Stefan
