This is highly unlikely though and is still a big security hole to leave open.Ģ. When you hit your VPN Provider IP with your dynamic DNS, traffic is getting passed through. Your VPN Provider has no firewalls in place and you are being given a public IP address visible to the Internet.

So there are one of two reasons that bridging your network adapters is working:ġ.

When you then use this DNS name, it is instead pointing to your VPN provider which will be blocking traffic from going into their network for their users security, instead of that request landing at your router. The issue when you connect to a VPN Service Provider is your external IP changes, so your dynamic IP is being reported to your Dynamic Name provider is your VPN Providers. Your dynamic name service provider will have an application running on your PC which regularly reports back your public IP address (that of your ISP) so when you use your host name external to your network, the request is sent to your router and then onto your home PC. There should be no noticable performance hit, but bridging your Viscosity adapter to your Local netowrk does open a security hole as you are essentially linking two networks together with no firewall or security in between.It opens up a way for anyone in the same VPN Network as you (or the internet if your VPN connection gives you a public IP) to access anything on your Local Network, or if you VPN home, a way for the network you are on, or again the Internet if you have a public IP address on your local area connection to access your home network.Īs for the problem at hand, I'm afraid I'm not 100% sure of your scenario, are you able to elaborate a bit more? From what I can understand you have a VPN Server at home that you can connect back to while you are away with a laptop (for example at a hotel), and bridging your Internet Connection (local area network) and Viscosity adapter on your laptop while away resolves a DNS issue looking up computer names when you have established a VPN connection back home.
