Please bear with my noob question here. So work has a site let’s say vpn.xyz.com at 12.1.1.12. When I traceroute to it from home it basically goes from a few routers to the wan link at work, on to 2 more hops inside the network (one other device and then the firewall—50.1.1.1 then 60.1.1.1 ) and on to the destination.
My question is how is the vpn’s ip address being advertised even when it’s behind other devices? The isp’s router on site connects to a L3 switch. from what I see it’s all default and static routes (no bgp etc). Could this just be a previous arrangement with the isp? How do I verify the method being used?
