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.

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.
