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

I am trying to do this remotely, but afraid I may lock myself out : )

We have a phone system and ports forwarded to the phone box. But we are getting hit from hackers.  the manufacturer is saying to whitelist just their IP addresses.

I am new to firewalls.

a) is this something this model can do?
b) how can I do that?

right now under firewall, it's set to nat only.  they have other choices of low medium and high.  once it's turned on to low, NAT stays on and I can add IPs to a white list?

think this is something I can do remotely or better to be on site so I don't lock myself out ?

You can do this remotely. You may want to add your working Ip address from your remote location 1st so you don't get locked out for some odd reason. Typically, those units are Ip#1, Ip#2, Ip#3, etc... And everything else is filtered and dropped. However, understand that the "whitelist" is considered your SAFE list. The way your question was worded it kind of sounded like you were going to whitelist the hacker Ip's? Do not do that.  Only whitelist the Ip addr. that you know and trust to achieve you goal. Everything else will get filtered.
