How does DHCP work with VPN?

DHCP requires a link layer which doesn’t really exist for VPN clients. Usually, a routed VPN connection is used and the VIPAP pool is used instead of the non-existent DHCP pool. With a bridged VPN connection, the VPN client uses an address in the same subnet as the VPN server.

Does VPN change default gateway?

A VPN will only be your default route if it’s intended to provide your Internet access. If it’s just intended to provide you access to specific subnets on the other side of the VPN, then specific routes will be used to just those subnets, over the VPN.

Does DHCP assign default gateway?

A DHCP server is responsible for allocating IP address and other information to requesting clients. The DHCP server is configured with a range of IP addresses that it can assign and also with other settings like DNS servers, default gateway addresses etc.

What is VPN client address?

A virtual private network (VPN) gives you online privacy and anonymity by creating a private network from a public internet connection. VPNs mask your internet protocol (IP) address so your online actions are virtually untraceable.

What is VPN default gateway?

The default gateway is the access point between your local network and the rest of the internet. It’s a single piece of hardware through which all devices on your network can send and receive data.

How does the virtual adapter driver respond to the DHCP packets?

When the virtual adapter driver receives the DHCP Discover and DHCP Request packets, it responds to the DHCP Offer and DHCP ACK by using the VPN Tunnel Server IP ( 10.200.200.200 ), which is provided by the VPN service.

What is the difference between a bridged VPN connection and dhdhcp?

DHCP requires a link layer which doesn’t really exist for VPN clients. Usually, a routed VPN connection is used and the VIPAP pool is used instead of the non-existent DHCP pool. With a bridged VPN connection, the VPN client uses an address in the same subnet as the VPN server.

How does a VPN Server assign an IP address to a client?

Maybe when a client connects to a VPN Server, the VPN server makes a virtual network interface on the VPN Server to give the client a Layer 2 presence on the remote network, and the VPN Server initiates DHCP DORA process by proxy on behalf of the remote client, and then the DHCP server on the remote network assigns an IP address

What is this message coming from the VPN client?

This message is coming from the VPN Client, it is the client’s retransmission requests for a dhcp address. On the client logs you should see these same retransmits. In your logs I see the outbound UDP connection build but I do not see a subsequent inbound UDP connection built.
