    Default Linux Internet Connection With ISPs

    Hello everybody,

    i have two ISP line in my network and which is connected to proxy server
    i have 3 NIC in my proxy server (Centos )

    eth0 == LAN IP=192.168.1.1
    eth1 == ISP1 IP=192.168.2.1
    eth2 == ISP2 IP=192.168.3.1

    internet works fine when i configure only one Gateway , but when both ISP's Gateway are configured internet doesn't works.

    please help me to configure 2 ISP . What is best solution to configure this ?

    You need to setup correct routing table. When you connect to two ISPs both will assign different gateway to route traffic. You can only use one gateway to send traffic or defines rules to send half traffic to ISP1 and rest to ISP2. The command you need to use is route to verify current routing table.
