Hi Petter,

I tried that with 10.0.0.1, 185.150.99.255 and, to go safe, 8.8.8.8
No effect. My ISP (ewetel) doesn't tell anything about DNS's.

And, with dhcp disabled on the router, WLAN- and LAN-clients as well as 
DI of the network-installer work fine with 10.0.0.0/8 IP address, 
default gateway 10.0.0.1 and DNS entries 10.0.0.2, 10.0.0.1 and 
185.150.99.255

Only after installation tjener has replaced the three DNS's by one: 
127.0.0.1 and get's no contact outside the LAN. If I replace the entrie 
127.0.0.1 in /etc/network by 10.0.0.1 I get outside, but gosa isn't 
useable from the LAN.

So my approach would be to get the named three DNS's in 
/etc/resolv.conf, but I have no idea where to force that.

Kind regards
