done.
preco tam mas tieto riadky ?
up route add -net 158.193.83.90 netmask 255.255.255.0 gw 192.168.1.1
down route del -net 158.193.83.90 netmask 255.255.255.0 gw 192.168.1.1
server vyzera ze mas nastaveny ok. ak sa z neho dostanes do sveta tak je to ok. skontroluj si ci mas hore aj druhy interface (smerom do lan).
skus pingnut nejakeho hosta v lan
potom cez iptables zapni maskaradu :
iptables -t nat -A POSTROUTING -s 192.168.0.0/16 -o eth0 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
Na hostoch potom nastav ako default gw ip interfacu na lan strane a DNS server taky isty ako server. A ked ti toto pojde zacni sa hrat s dhcp
