feat: vpn like resolving

[shoriwe]

fullproxy should be able to forward traffic over a virtual network interface to a set of fullproxy running slaves.

Main ideas

Setup a wiregard or netgard running in master node and have the client resolve all the traffic comming from the VPN protocol though the slave or vice versa.

Main goals:

• Have the ability to send and receive any kind of traffic between machines connected from the slave side.
• Have the ability to listen to a specific port in the master side but traffic forwarded though slave.

Example

Setup

• Master running
• Slave connected to master
• Slave network is 192.168.50.1/24.
• Slave local IP is 192.168.50.101

Capabilities

• Master can listen at any port on 192.168.50.101 (Slave's IP)
• Any traffic at 192.168.50.1/24 is resolved though the VPN tunnel between the master and slave: Meaning if a ping is executed from the master side. traffic will be redirected by the tunnel.
• The same when opening connections.
