The problem that local Internet access cannot be achieved after a VPN connection is established

I am new to a company in charge of network maintenance, the company's server is in the DMZ area, so if you want to perform remote management, you can only connect to the VPN.

However, it is strange that the local computer cannot access the Internet after the VPN is connected. If you find a method on the Internet to disable the default gateway on the remote network, you can access the Internet locally, but cannot connect to the DMZ zone.

Later, I found a method after multiple searches.

1. Connect to the VPN

650) this. width = 650; "title =" TM20130930145753 "style =" border-left-0px; border-right-width: 0px; background-image: none; border-bottom-width: 0px; padding-top: 0px; padding-left: 0px; padding-right: 0px; border-top-width: 0px "border =" 0 "alt =" TM20130930145753 "src =" http://www.bkjia.com/uploads/allimg/131227/225513A01-0.png "width =" 244 "height =" 143 "/>

2. Open VPN properties --- network --- ipv4 --- advanced

650) this. width = 650; "title =" TM20130930150326 "style =" border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-right: 0px "border =" 0 "alt =" TM20130930150326 "src =" http://www.bkjia.com/uploads/allimg/131227/2255132U2-1.png "386" height = "421"/>

Remove the default gateway from the remote network and click OK.

3. Open cmd to add route entries

650) this. width = 650; "title =" TM20130930150912 "style =" border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-right: 0px "border =" 0 "alt =" TM20130930150912 "src =" http://www.bkjia.com/uploads/allimg/131227/2255132035-2.png "493" height = "53"/>

If you are sure that the VPN will be used after the computer is restarted, add-p after route add. this parameter is a permanent route. Otherwise, remove-p.

4. check whether this route entry exists in the route table.

650) this. width = 650; "title =" TM20130930151254 "style =" border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-right: 0px "border =" 0 "alt =" TM20130930151254 "src =" http://www.bkjia.com/uploads/allimg/131227/2255132917-3.png "495" height = "68"/>

 

 

In this case, local Internet access and VPN network operations can be performed simultaneously.
