How to configure suse linux dual network card and dual gateway? in view of this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

The company has a SUSE LINUX server that needs two networks, one of which is 192, which is used on the OP management platform system. One is the B network, the network segment is 202, which is used to access the external network. We all know that it is impossible for a computer to have two gateways, because the default gateway (default gateway) can only be one. If we frequently switch gateways and DNS to access the Internet and OP management platform system, it will bring great inconvenience to the work, so I use soft routing to achieve dual network cards and double gateways to achieve simultaneous access to the Internet and OP management platform system.

Let's look at the specific operations:

1. Edit the configuration file of the network card:

Open the Nic configuration file with an editor such as vi, and configure it as follows:

(1) / etc/sysconfig/network/ifcfg-eth-id-68:b5:99:76:83:a2 # 192 network segment connecting OP management platform system

DEVICE= "eth0"

BOOTPROTO= "no"

IPADDR= "192.168.192.10"

NETMASK= "255.255.255.0"

ONBOOT= "yes"

(2) / etc/sysconfig/network/ifcfg-eth-id-68:b5:99:76:83:a4 # 202network segment connects to the external network

DEVICE= "eth2"

BOOTPROTO= "no"

IPADDR= "202.106.128.204"

NETMASK= "255.255.255.248"

GATEWAY= "202.106.128.206"

ONBOOT= "yes"

2. The two gateways are 192.168.192.1 and 202.106.128.206 respectively

Vi / etc/sysconfig/network/routes

Add a soft route:

192.168.192.0 192.168.192.1 255.255.255.0 eth0

Then wq saves and exits.

Or enter the command directly.

# route add-net 192.168.192.0Universe 24 gw 192.168.192.1 dev eth0

Finally, you need # rcnetwork restart (restart the network service)

Then # netstat-rn to see the new route entries.
