Customize WAN with two IPs: exteral and network internal

[Lucyk]

Hello.
My internet service provider is a local network, each subscriber is assigned his own static IP. There is an option for getting separated real IP. When a subscriber uses an option that provides real IP, internet service provider recommends following settings for Windows-based computers:

IP: 91.23.45.12
Subnet Mask: 255.255.255.128
Default Gateway: 91.23.45.1
DNS: 192.168.5.254

And pointing out second IP:
IP: 192.168.2.56
Subnet Mask: 255.255.240.0

Please suggest me a way to customize my WL-500gP with these settings.

Well, it depends to your desire - when you see any advantage to use the local network (for what should it be?) then download for instance "advanced ip scanner" and run a check which ip's are already used in local network.
Real IP means you have to connect it to the wan port of your router, using static ip, gateway, dns aso.
When you want to use existing local network, you should use a switch or an bridged router in front of your wan port. Your private network should be connected behind your router on a different subnet eg. 192.168.150.x or similar. Any service (intranet-server) for the existing local network must connected in front of your wan port.
Anyhow, I don't see a real advantage to use such kind of configuration. It would make sense only (for me) for closed communities or larger family network.
Hence, I would suggest to use just the "real IP".

Hi,

I have the alike problem.
Want my Asus router to replace PC run Linux router/server.
For tests I need to connect my Asus wl500gV P2 to one of switch port via WAN port on router and have my laptop connected to LAN port on a router for configuration purposes.

PC run Linux router/server already runs DHPC server, assigning dynamic IP range 192.168.1.x

Is it ok, to set DHPC server on Asus router on
and set IP range like suggested by you - 192.168.50.x
to have laptop connected to Asus router to get connected to the Internet ?

How to select gateway and DNS on Asus, as both local network and subnet run dynamic IP ?
