Have been to this site before and received excellent help especially from rw120555. The relevant post at : http://forums.anandtech.com/message...8911&highlight_key=y&keyword1=laptop wireless

have come back for the second stage of this setup. I have been able to successfully connect all homepna machines and the laptop wirelessly to the linux box and netgear mr314 wireless router and they all have internet connection sharing and file sharing. I accomplished this by using the Windows XP box with dual ethernet (homepna and 10/100 mbps nic) as a software homepna and ethernet bridge. The linux box homepna ethernet card is setup for connection sharing and as dhcp server with IP 192.168.0.1. The netgear MR314 wireless router is set at 192.168.0.2 with dhcp disabled. the Linux box is connected to the homepna network and the MR314 router. lets designate pc1 as the linux box, pc2 as winxp and pc3 as winME. PC2 has homepna and 10.100 nic installed. PC3 has homepna only.
My next endeavor is to try to setup this bridge functionality in linux so that I dont have to always keep the WInXP box on. Tried to research but the documentation befuddles me. Cant seem to get it to work. I have the linux box with eth0 (homepna) and eth1 (10/100 mbps nic) . Mandrake control center has setup eth0 for connection sharing and gave it an IP of 192.168.0.1, netmask 255.255.255.0, network 192.168.0.0, broadcast 192.168.0.255. What settings do I need for eth1 ? When I try to setup the Linux box for connection sharing and dhcp server using eth1 (10/100 nic) it also works but cuts off the homepna networked PCs unless the software winxp bridge is on. Likewise, if the linux box is setup for connection sharing and dhcp server using eth0(homepna), the laptop gets cut off ( because it relies on the ethernet 10/100 mbps connection) . In the future If I can get the linux bridge working, PC2 will only have 10/100mbps and PC3 will only have homepna while the laptop will have both wireless and 10/100 nic connetion. If you cant give me specific linux recommendations on configuration, maybe just an explanation of the underlying theory and what subnets, ip and netmasks to use would be helpful. Thank You Very Much.
