I have a linux system with two network interfaces (eth0 in x.x.x.0 and eth1 in x.x.y.0). Is there any posibility to add some route policy to send all the traffic to network x.x.y.0. I would like even the traffic from eth0 to be send to eth1's network.
I cannot delete the direct connected networks from the routing table so all the traffic from x.x.x.0 network is send to eth0.
i have two ethernet interfaces namely eth0 and eth1.
Now i want to implement an advance routing rule but i am totally new to firewall/routing rules in linux/CentOS.
Here is what i am trying to do:
So both my interfaces are up and connected to internet.
I am trying to recreate this behaviour using iptables under ubuntu :
Let's say we have 3 interfaces : eth0, eth1 and eth2. I must forward the traffic through a VPN interface vpn0. Then, I must assure that the incoming traffic through the VPN is redirected correctly to the right interface ( eth0, eth1 or eth2 ).
I have searched long for an answer, but didn't find anything truly usefull.
I need the information regarding multiple interface card.
My Scenario is:
Eth0: 172.X.X.X / X.X.X.252 GW 172.X.X.105
Eth1: 192.168.X.X / X.X.X.0 GW 192.168.1.1
My Requirement is that:
Eth0 traffic out/in gateway 172.X.X.105
Eth1 traffic in/out gateway 192.168.1.1
Mean that traffic generate from eth0 forward to its own gate way, same as eth1.
I am using the elastix server (centos) with two
Scenario:
eth0 = LAN
eth1 = Internet
eth2 = Internet
I would like to force all traffic from eth0 between ports 1-443 through eth1 and the rest on eth2.
I have a server running ubuntu 10.04 with four interfaces. eth0 and eth1 have static WAN ip's, and eth2 and eth3 are connected to two separate NAT networks 192.168.0.0/24 and 192.168.1.0/24 respectively. eth0 is masqueraded and NAT traffic from eth2 is forwarded to it.
I'm wondering about this, and I can't seem to find an explanation on the internet.
I have a linux gateway which has multiple interfaces:
eth0: external ip
eth1: 172.16.1.1/24
eth2: 172.16.2.1/24
ip_forward is enabled.
IPtables is configured to NAT traffic from eth1 -> eth0 and eth2 -> eth0.
Here is my scenario: i have this server with 2 nics, each one with different IPs, connected to differents routers.
Almost everything is configured whe way i need. Traffic coming from eth0 exits using eth0, traffic coming from eth1 exits using eth1. And there is a default gateway configured.
My embedded Linux board has 3 interfaces:
eth0 - For all outbound traffic
eth1 - A hardware loopback (traffic leaves board, but comes immediately back in the same port)
lo - Standard loopback interface
ifconfig reveals the following:
eth1 Link encap:Ethernet HWaddr AA:BB:CC:DD:EE:FF
inet addr:169.254.1.1 Bcast:169.254.255.255 Mask:255.255.255.255
