method one
IP network is: 192.168.4.213, network gateway: 192.168.4.1
WAN IP is: 58.200.200.15 subnet mask: 255.255.255.128 gateway: 58.200.200.1
1. When configured as a server within the network and external network IP IP way, set just outside the network IP gateway, do not set the network IP gateway.
As follows:
vi /etc/network/interfaces
Inside modified as follows
auto eth0
iface eth0 inet static
address 192.168.4.213
netmask 255.255.255.0
auto eth1
iface eth1 inet static
address 58.200.200.15
netmask 255.255.255.128
gateway 58.200.200.1
Note: We do not set the gateway to eth0 (internal network), save and exit
2. Restart card, Ubuntu restart card command is:
/etc/init.d/networking restart
3. Routing manually set the server
route add -net 192.168.4.0/24 gw 192.168.4.1 dev eth0
Note: manually add routes, does not take effect after server restart
Method Two
vi /etc/network/interfaces
Modifications are as follows
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 211.x.x.x
netmask 255.255.255.x
gateway 211.x.x.x
dns-nameservers 114.114.114.114 119.29.29.29
auto eth1
iface eth1 inet static
address 10.16.16.15
netmask 255.255.255.0
up route add -net 10.0.0.0 netmask 255.0.0.0 gw 10.16.16.254 eth1
**
Only set one gateway, the gateway using another route, and a network interface specifies the gateway ip
