Dual-nic CIDR Block same Intranet/Internet access

Department companies use dual-nic connections, but the Intranet segments are the same. For example:

1. Intranet Nic IP Address: IP address of the internal server of 192.168.1.0/24 Intranet Gateway: 192.168.1.254 where the ERP server 192.168.1.253

2. Internet Nic IP Address: 192.168.1.0/24 Internet access network segment Internet gateway: 192.168.1.1

In this case, access to the server in the network segment of Internal 1 may fail. If you still cannot access the server in the Intranet segment after using the route add command, because the IP addresses at both ends are repeated, using the route print command, we can see that the gateway to 0.0.0.0 is 192.168.1.1 by default. In fact, 192.168.1.1 is an Internet gateway rather than an intranet gateway, which causes access to the Intranet server to fail.

Add a route table to the host.

Route add-P 192.168.1.253 mask 255.255.255.255 192.168.1.254 metric 1

Then you can access the Intranet ERP server.
