Are you talking about my modem? I'm currently using Netcomm NB1300 Plus 4

I'm just trying to forward my DNS port to port 53 so that everyone can see 
my websites.

With the DNS ports, is it a TCP, UDP or both protocol?

And when you forward this port, is it actually your DNS IP Address or your 
own machine's IP Address.

Thanks.
