[En-Nut-Discussion] Change the IP/gateway

[Sigurd Kleppan]

Oki, thank you Ole!

Is it on this code you configure the IP then...??
F.eks:

 confnet.cdn_ip_addr = 192.168.1.2;
 confnet.cdn_ip_mask = 255.255.255.0;
 confnet.cdn_gateway = 192.168.1.2;


Is it possible to configure a DNS server adress?

Regards
Sigurd Kleppan
