Two subnets connection problem

By russelsc ·
Hi All. I have a Netgear WGR164v9 wireless router connected to internet directly by public IP and this router performing DHCP for wireless LAN ip subnet is 192.168.1.x. A server (DNS,DHCP & RRAS with NAT) connected with this router by ip 192.168.1.6 which has another subnet 192.168.10.x for LAN PCs. In this situation everything is fine like internet browsing. The only problem is wireless PCs (192.168.1.x) can't connect with wired LAN PCs (192.168.10.x). The router ip is 192.168.1.1. Can anyone please tell me how can i configure to connect those two subnet's PCs?

Routing configuration

by ossyemeh In reply to Two subnets connection pr ...

If your router have another Ethernet port, link the wired PCs to the router using cable and configure the two interface to see each other. or if you can configure the two networks to use 192.168.1.X subnet

Routing configuration

But right now with above configuration wired PCs (192.168.10.x) can connect wireless PCs (192.168.1.x). Then where's the problem?

NAT

by Churdoo In reply to Routing configuration

If I understand your setup correctly, your server 192.168.1.6 has 2x NIC's with one being on the 192.168.1.0 network and the 2nd NIC is on the 192.168.10.0 network? This means that all of the PC's on the 192.168.10.0 network are connected to a distribution behind the server, with the server providing routing and/or NAT as you've described. If the server is running NAT, it's NAT on the server that's stopping the 192.168.1.0-->192.168.10.0 traffic.

The first router 192.168.1.1 is probably also providing NAT, so you probably don't need to be running NAT on the server as well (outbound 192.168.10.0 traffic is double-NAT'd in your case). You should be able to reconfigure RRAS to disable NAT and provide routing between the networks and to the internet without losing any functionality.

Two subnets connection problem

by russelsc In reply to Two subnets connection pr ...

Thanks to all. I have disabled the NAT on the which having 2 NICs server but nothing helped. Still i'm trying to fix the problem but i cant much more on that because users are facing link down so i m moving slowly. For your better understanding let me figure out the infrastructure a bit more: ISP--->WiFi Router (DHCP)---->Server (DHCP)----->All PCs via a normal 24 port switch I------->All WiFi PCs.

Wifi having public ip for connect internet and local ip 192.168.1.1 and its the WiFi gateway. The server having 2 NICs, one is 192.168.1.6 and other is 192.168.10.1 and this is the gateway address of all wired LAN PCs. Server having NAT that is forwarding all request from 192.168.10.x to 192.168.1.6. Hope this information enough to make clear concept. Now all wired LAN PCs can ping and connect all wireless PCs but wireless PCs cant. Kindly help me to connect both subnet that all PCs from those two subnet can connect each other.

Request for Clarification

by CG IT In reply to Two subnets connection pr ...

why do you have a WiFi router in there when from what you describe, you need an Access Point?

If your router doesn't support multiple LAN subnets, then even with a routing protocol enabled, it's not going to route to a different subnet on the LAN.

Not just NAT, but routing too

by Churdoo In reply to Two subnets connection pr ...

Only disabling NAT would not have solved the problem. Step 2 of the solution is proper routing.
1. Disable NAT on the server
2a. make sure your server will pass inbound traffic destined to the 192.168.10.0 network from the external interface to the internal interface
2b. put a static route in what you're calling your wifi gateway 192.168.1.1 to route 192.168.10.0 traffic to the server external interface 192.168.1.6

Perhaps you should hire a local consultant to assist as they will be able to do this for you quickly.
