This configuration can only work if you are connected to the internet directly without any NAT router, and if you have set your firewall to allow incoming connections on all ports greater than 1024.

Setting Up a SonicWall with Nextiva | Nextiva Support Jul 09, 2018 Mar 28, 2019 · A VPN that uses a NAT firewall assigns each user a unique private IP address. It extends all the benefits of a wifi router’s NAT firewall, as discussed above, to your VPN connection. The downside is that even though you are protected from unwanted communication, your device could be more easily tracked by the VPN provider or a third party. Other benefits of NAT include security and economical usage of the IP address ranges at hand. The following steps explain basic Cisco router NAT Overload configuration. NAT overload is the most common operation in most businesses around the world, as it enables the whole network to access the Internet using one single real IP address. Basically NAT allows a single network device (e.g a router, firewall etc) to act as an agent between a private local area network and a public network such as the Internet. The purpose of this NAT device is to translate the source IP addresses of the internal network hosts into public routable IP addresses in order to communicate with the Internet. NAT can be configured in various ways. In the example below, the NAT router is configured to translate unregistered (inside, local) IP addresses, that reside on the private (inside) network, to registered IP addresses. This happens whenever a device on the inside with an unregistered address needs to communicate with the public (outside) network.
That said, there are completely valid and workable circumstances where a network administrator may require local NAT traversal technologies to be deployed on their router/firewall. For example, the SIP ALG on Cisco routers is known to work well with our service and we recommend it (our server-side system will not be engaged at all in this

Jul 14, 2017 · It’s important to use at least one type of a firewall – a hardware firewall (such as a router) or a software firewall. Routers and software firewalls overlap in some ways, but each provides unique benefits. If you already have a router, leaving the Windows firewall enabled provides you with security benefits with no real performance cost.
