iptables and MASQUERADE
Imam ovako podesen iptables, medjutim masquerade mi ne radi bas najbolje iz lokalne mreze :(, naime DNS lookup prodje i provali tacnu adresu medjutim ne moze da joj pristupi. probah sa pingom.
Sta nisam dobro podesio.
PS koristim mandrake 8.1
#!/bin/sh
# Load the NAT module (this pulls in all the others).
modprobe iptable_nat
# Turn on IP forwarding
echo 1 > /proc/sys/net/ipv4/ip_forward
# In the NAT table (-t nat), Append a rule (-A) after routing (POSTROUTING)
# which says to MASQUERADE the connection (-j MASQUERADE).
/sbin/iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -j MASQUERADE
# Allows forwarding specifically to our LAN
/sbin/iptables -A FORWARD -s 192.168.0.0/24 -j ACCEPT
# Allow dhcp requests
/sbin/iptables -A INPUT -i eth0 -p udp --sport bootpc --dport bootps -j ACCEPT
/sbin/iptables -A INPUT -i eth0 -p tcp --sport bootpc --dport bootps -j ACCEPT
/sbin/iptables -A INPUT -i eth0 -p udp --sport bootps --dport bootpc -j ACCEPT
/sbin/iptables -A INPUT -i eth0 -p tcp --sport bootps --dport bootpc -j ACCEPT
# Allow dns requests
/sbin/iptables -A INPUT -i eth0 -p udp --dport domain -j ACCEPT
/sbin/iptables -A INPUT -i eth0 -p tcp --dport domain -j ACCEPT
