I am trying to do this remotely, but afraid I may lock myself out : )<br />
<br />
We have a phone system and ports forwarded to the phone box. But we are getting hit from hackers. &nbsp;the manufacturer is saying to whitelist just their IP addresses.<br />
<br />
I am new to firewalls. <br />
<br />
a) is this something this model can do?<br />
b) how can I do that?<br />
<br />
right now under firewall, it's set to nat only. &nbsp;they have other choices of low medium and high. &nbsp;once it's turned on to low, NAT stays on and I can add IPs to a white list?<br />
<br />
think this is something I can do remotely or better to be on site so I don't lock myself out ?

Can I whitelist IP addresses on the verizon version of Actiontec GT784WNV router

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
