Netgear DG814 > NAT to No NAT query

[jatkinson]

I have a Netgear DG814 ADSL router installed that is currently running as a NAT device, with the default IP Address of 192.168.0.1 on the LAN side.

I understand that I can turn NAT off so the router becomes just a gateway (is it also sometimes called a bridge?) running as a No-NAT router.

My query is very simple therefore, although I just wanted to confirm.

If I turn NAT off on the router, will the IP address of the router remain as 192.168.0.1 so I can connect back in via browser to switch back to NAT if I desire?

Thanks

IP Host devices always have an address. If you just disable DHCP to disable NAT server features on the router, and change nothing else, the router will still have its host address and can be contacted on that.

Problem: if you manually assign IP addresses to your connected worksations, you may well decide on a IP subnet that is different from the 192.168.x.x subnet of the router.

You will need to manually change the IP of the workstation to be in the same subnet to access the router. In your example, if the router is at 192.168.0.1, manually configure the IP of the workstation to the same subnet, say 192.168.0.2 to access the router device setup.

Hi there

Thanks for your reply, to explain further I am trying to configure a firewall behind the router, therefore wanting the public static address my ISP gave me to be on the WAN side of the firewall and for the router to pass traffic straight through. Further info from elsewhere has given me the impression this can't be done as I would need 2 static addresses from my ISP. My concern was that if the WAN side of the firewall had my public address, how could I contact the router that has a 'fixed' 192.168.0.1 address but I guess that the requirement for having 2 static addresses may have answered that.

A little confused so any further advice would be greatly appreciated.

Thanks

Your first "firewall" should be to have the workstations behind a NAT router. This is incredibly effective as a "firewall."

I get that. What I am looking for is a way to VPN through the ADSL router to the firewall behind as the VPN endpoint. This firewall will then be the NAT router between the WAN and the LAN, however I don't look to be able to allow the ADSL Router to be a bridge to pass VPN traffic over to the firewall/NAT router/VPN endpoint.

Buy a broadband router that can function as an VPN endpoint. If you only need one VPN connection, most consumer grade broadband routers would offer you at least one VPN passthru connection. You will have to spend slightly more to allow multiple VPN endpoints, but several consumer grade routers offer this feature. For one, look to the Linksys product line.

OK thanks for the tip but I'm actually keen to use the VPN features of the firewall machine not a router. I'll look at lynksys products to see if they do a router that allows VPN passthrough to another NAT configure firewall/router.
