Hello,
I'm trying to configure a ubuntu server to be a router. This is my interface configuration (eth2 connects to my WAN, eth0 to my LAN):
auto eth2
iface eth2 inet static
address 192.168.0.249
netmask 255.255.255.0
gateway 192.168.0.1
broadcast 192.168.0.255
auto eth0
iface eth0 inet static
address 192.168.100.1
netmask 255.255.255.0
This is the router information:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2
0.0.0.0 192.168.0.1 0.0.0.0 UG 100 0 0 eth2
And this is dhcp configuration:
subnet 192.168.100.0 netmask 255.255.255.0 {
range 192.168.100.101 192.168.100.254;
option domain-name-servers 201.70.86.133;
option routers 192.168.100.1;
authoritative;
}
I'm then connecting a mac os x by cable on eth0. This is en0 interface configuration:
en0: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
ether 00:26:bb:5d:82:b0
inet6 fe80::226:bbff:fe5d:82b0%en0 prefixlen 64 scopeid 0x4
inet 192.168.100.101 netmask 0xffffff00 broadcast 192.168.100.255
media: autoselect (100baseTX <full-duplex>)
status: active
And this is the routing table:

When I ping 192.168.100.1, it works. When I ping 192.168.0.249, it also works. However, when I try to ping 192.168.0.1 it does not.
Does anyone has any way to solve this? Is there a way to debug it?
Thanks,
