So, if my WAN IP adress is 83.238.*.* then i need to run DHCP server in
the same class of if address. But, if got only this address and i will
setup in eg: 83.238.55.10 to 15 range for eth0:0 and there is a machine
with WAN address like 83.238.55.13 if gonna to make IP address
colission? or then it will be avalible only as LAN Address for my server?
/Best Regards
