VPN penetration Function

The VPN penetration function of the network router is described in detail. The router VPN penetration function does not mean creating a VPN channel, but allows a VPN channel created by other terminals to pass through it, next I will take a network-connected router as an example to introduce it in detail.
1. The number of VPN channels through the Network Gateway depends on the situation. When there are more than one target gateway connected to the VPN, the key lies in whether the connected VPN gateway supports NAT penetration detection, that is, whether the NAT-T is supported. If yes, the channel is created successfully and you can perform VPN transmission.
2. The three computers behind the network router initiate a connection to the same VPN on the Internet at the same time. Because of the NAT Function of the router, all the private IP addresses are mapped to the same public IP address, the VPN gateway on the Internet cannot identify each computer and treat them as the same computer, but if VPN gateway supports NAT-T, it can clearly identify each computer. Another case is www.2cto.com. Even if a VPN connection is created, file transmission cannot be performed. For example, the Network parts FVS318V3 and FVX538 must be changed.
4. In the Rule option in FVX538, there is a Drop fragmented IP packets, which is selected by default. If the file cannot be copied, you can try to cancel it.

The above are some common knowledge about creating a VPN connection for the Network Gateway Router. If you need it, you can understand it. This article is from
