Pirmiausia, tai dhcp tau net nepasileidzia kaip itariu, nes

# we want the nameserver to appear at a fixed address
# host name_server {
next-server ns1.telecom.lt;
hardware ethernet 12:34:56:78:AB:CD;
fixed-address 212.59.0.1;
}
uzkomentuota viena eilute perdaug ir cia tikrai telekomo dns servas ne
prie ko.

dabar darai pagal shema internetas <-wan interfeisas-> routeris
<-routerio vidinis interfeisas-> tavo servo eth1 su ip is to pacio
potinklio kaip pas routeri lan, i eth0 jungi switcha prie kurio
sujungtas visas tinklas, ant eth0 dedi ip koki nori tik ne ta pati
potinkli kuris uzdetas ant routerio, tada jungi forwardinima ir
masqueradinga, viskas turi veikti. Serve nurodomas, kad default gw yra
tavo routeris, o tavo kompams tinkle nurodomas default gw tavo servas.
