# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

auto lo eth0 eth1

iface lo inet loopback

iface eth0 inet static
address 192.168.3.7
netmask 255.255.255.0
network 192.168.3.0
broadcast 192.168.3.255
gateway 192.168.3.1

iface eth1 inet static
address 216.206.xxx.xx
netmask 255.255.255.128
gateway 216.206.xxx.1
broadcast 216.206.xxx.127
network 216.206.xxx.0
gateway 216.206.xxx.1

This is how I have my network interfaces configured. I can ping the 216.206.xxx.xx address from anywhere on the internet but I can't get to the 192.168.3.7 from the other side of my network. I want to have this machine accept traffic on either network and send back out the network it came in on and it doesn't appear to be working.

Any Help will be great!

As a root type
#ifconfig

at the prompt show here its output.


And i think eth1 show ur public ip, so for security reasonse don't show ur public ips like this , instead show it like this x.x.x.x,

-jack

So, check u might be behind firewall and its blocking the traffic from outside.


-jack

No firewall. The 216.206.x.x is routed via BGP on a T3 and the 192.168.3.7 is on the inside private network which goes through another router that has a iptables firewall on it but that should be messing with the traffic coming in on the 216.206.x.x network

Enable ip_forwarding:

When I attempt to traceroute out I can't get very far and it goes through my nat box and out the other link not my 216.206 link. What appears to be happening is it is send it out that 192.168.3.1 gateway with a source address as my 216.206.x.x address
