Oh, one thing I want to mention is, that I had an issue with shorewall at the installation. If you use shorewall on a machine with 2 interfaces (a green and a red one) it is not allowed to connect both to same switch. If you do so the behavoir of the firewall then is very stange. The client somtime have access sometimes not. I found that in the FAQ of shorewall. Maybe that should be mentioned in the install section of the manual.witch

Hi @flatspin ,

Can you please share your network configuration page, in order to help you completely.

Hi @Nas ,

thank you for your reply. I solved the problem allready. I just changed wirings. Then everything went fine.
Fortunately I had an old wire directly to the router, so I didn’t have to use the switch. I pluged in that cable an
everything was o.k. I’m affraid I did a “fools firewall”.

I just wanted others to know, so that they are not doing the same mistake.
