Subnetting
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?

Thanks. We'll let you know when a new response is added.

OK, seems that you are only missing a little detail.

Based in your scenario, I assume that your wireless clients are provided a Default Gateway of 192.168.1.1, which is your wireless router.

If this is the case, you must have a static route between 192.168.1.X network and 192.168.10.X network with a gateway of 192.168.1.6 from the wifi side, and a static route of 192.168.10.6 from the 192.168.10.X side.

Think this way, your RRAS server (without any further detail from your config) is the *only* machine that knows these two networks. So, it must be the gateway and allow routing between them.

As almost allways there is more than one way to put that to work, but that depends on further information about your wireless router (it’s cappabilities which i personnaly don’t know), and if the phisical network can be changed.

Thank you very much Saturno. I have followed ur comments and has been solved the problem accordingly. Thank you again, u r really wise in networking.

    Saturno is correct; take a look at the following link, it's the "Configuring Static Routes" section from your specific routers manual. It also has an explanation of when a static route may be needed, and exactly how to setup your router. It's fairly well written and easy to follow, take a look. http://documentation.netgear.com/wgr614v7/enu/202-10178-01/WGR614v6-07-19.html Hope this Helps....Good Luck

    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.
