https://www.centos.org – I have a DELL running CentOS 5.4 with 2 active NICs, one with an external IP address (eth0) on 123.456.78.9 and another that is connected to our internal network (eth1), 192.168.2.x. When I reboot... [by scoopseven] (Distributions)

Stories similar to External traffic starts going over internal interface

ping breaks 3 years 22 weeks ago

I have implemented advance routing fo load balancing and a script for and fail over on a Linux machine which run squid and dansguardian for proxying, i have three interfaces on this machine which are

10.201.108.254 eth1 external interface connected to service provider 10.201.109.254 eth2 external interface connected to service provider

Hi,

My Ubuntu Box has 3 interfaces. eth0 (Internal 192.168.1.0/24) eth1 (External ISP DHCP) eth2 (External ISP Static IP) I need the outgoing traffic to internet for 1 of the internal pc (192.168.1.10) to only go only go through eth2.

How do i write using iptables to do the above? Thanks.

I would like to ask for a little help. I'm setting up a openvpn bridge in opensuse 12.2, I can connect to server, but I can't ping the server, nor anything that is behind server. Also, I can't ping the client from server.

Hi im fairly new to Ubuntu/Linux and i have somehow managed to get a server up and running. For the past few months i have been trying to get masquerading working but the more posts i read the more confused i am getting.

Could someone please help me or point me in the right direction.

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.

Centos server has two network cards:eth0: 192.168.1.1/24 - Internal networketh1: 172.18.18.2/24- External network connected to ISPISP Proxy server address: 172.18.1.1 Port 8080

I've got a small network, two interfaces, eth1(local, internal range 192.168.150.0/24) and eth0 external, static ip.

I wish to set up nat forwarding for the internal network but allow them to only connect to an external server 209.60.x.x and reject connections to all other external ips.

How do i only allow forwarding/nat to ip 209.60.x.x ?

We are connecting a server to our network via VPN (Client-Gateway). Is it possible to maintain the external IP address while the VPN is connected?

I have a server (Ubuntu 10.04 server) that has two NIC.
