Perforce Use

Okay I believe this will be my last question because this is what is confusing me at this point…

What IP address should I be putting in as the Device IP#?

Should it be the IPV4 from my Server Host Machine which is the machine that has the Perforce Server (NOT P4V or P4V Admin) installed or…should it be the IPv4 from my Client Machine with P4V/P4V Admin installed?

This is confusing the hell out of me!!!

I have the port 1666 open through my Firewall now, I have DynDNS setup in my DDNS as Static instead of Dynamic now…but when I do ipconfig on my Server Machine the ip I get back is 192.168.1.1 as my Default Gateway which is the same thing I get when I do ipconfig on my Client Machine as the Default Gateway. The only IP#'s that are different are the IPv4 on both machines which I believe are the real IP’s of these two machines and the Default Gateway is just a generic IP.

Anyway…when I try to input 192.168.1.1 as the Device IP# I get an error…but it will take either of the IPv4 which both begin with 192.168.1 but the last digits are different for both machines.

Which is the correct one to place in the Device IP# for Port Forwarding to work?
