I am currently trying to set up a home router using a machine running Ubuntu 12.04. The machine has two ethernet ports. eth0 is LAN and eth1 is WAN.
I have set eth0 to a static ip and have eth1 request an ip via DHCP.
/etc/network/interface
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 10.1.1.10
netmask 255.255.255.0
gateway 10.1.1.10
dns-nameservers 10.1.1.1 10.1.1.10
auto eth1
iface eth1 inet dhcp
This allows me to ping LAN computers, but I am unable to ping or access any external hosts. The modem is giving eth1 a valid ip address. The machine is setting it's LAN ip to 10.1.1.10 (to be moved to 10.1.1.1 when everything is working).
I have added the following to /etc/bind/named.conf.options
:
forwarders {
8.8.8.8;
8.8.4.4;
};
net.ipv4.ip_forward=1 has been added to /etc/sysctl.conf
.
$ route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default Vanir.local 0.0.0.0 UG 100 0 0 eth0
10.1.1.0 * 255.255.255.0 U 0 0 0 eth0
98.162.168.0 * 255.255.252.0 U 0 0 0 eth1
link-local * 255.255.0.0 U 1000 0 0 eth0
Does anybody see what I'm missing in order to allow both WAN and LAN traffic on my machine?
