Yes, that's most likely possible. Most VPN protocols like IPsec or OpenVPN are originally peer to peer, with client-server functionality often added as an option. Client implementations can usually only handle the client side, server implementations should be able to do peer to peer as well.......

The Internet represents a threshold moment for the communications realm in many ways. It altered the immediate end client of the network service from humans to computers. It changed the communications model from synchronized service to asynchronous, and from virtual circuits to packet-switched.......

for some reasons I don't want to go into (there is only one kind of router that can transmitt data throught that long internet cable) I have to have 2 NATS here is a picture of my network diagram I would like to ping the device on 192.168.89.240 from 192.168.1.4 I added the route to my......

I am learning about MPLS at the moment. I know that routers in general make forwarding decisions based on the destination IP addresses and available routes in the routing table. However, with MPLS it's different. MPLS uses labels. Why does MPLS uses labels instead of destination IP addresses......

That problem isn't specific to GRE tunnels but applies to tunnels in general. The most obvious example is when you create a client VPN with no split tunneling = all traffic should enter the tunnel, not just to intranet destinations. That means that you'd want the default route to point into the......

A fellow networking engineer recently remarked, “FRRouting automatically selects the correct [IBGP] source interface even when not configured explicitly.” TL&DR: No, it does not. You were just lucky. Basics first. BGP runs over TCP sessions. One of the first things a router does when......

The DHCP config looks OK, but I don't see how RO2 could know where those subnets are actually located - RO1 might use its local subnet addresses as source for the relay packets. RO2 either requires a default route via 192.168.25.26 or - better - specific routes for 192.168.15.0/24 and......

An open and modular architecture But first, let’s set the context of the discussion. NFV and uCPE are built on the idea of moving from a closed network appliance to an open and modular system. The example below shows the following layers, from top to bottom: Virtual network functions (VNFs): the......

IPv6 has been gaining traction since it was introduced and was intended as a solution to IPv4 address space constraints and security issues. Despite the clear advantages of the protocol, adoption of IPv6 throughout the industry has been hindered by a few factors, including misperceptions in IPv6......
