i`m deciding to buy a linksys router WRT54G which is below version 5 so i can flash right now i`m using a cable modem which is connected in my nic#1 i`m also using an external lan connection ( for for file sharing , which is a switch based network having over 100 users for file sharing connected at nic #2) my nic#2 only has ip 192.168.7.100 and subnet mask 255.255.255.0 other users are 192.168.7.X there is no DNS or gateway , we all can ping each other without problems and play games etc and share files now if i buy WRT54G , on broadband port i put my cable modem on the 4 wired ports , on #1 port i put my local lan connection which was in nic #2 and on the #2 port i connect to my pc nic and from settings i only allow internet bandwidth to my macid of lancard so ill use router (not to give me auto ips but manual) ill use my ip 192.168.7.100 , router woul be 7.1 ? ( ther is no 7.1 on the network at present and i can put gateway + dns of router to use internet) so would they both be bridged locally and i can use the broadband too ? as ill put my gateway and dns (ip of router ?) and is the router i m selecting is okay for this ? waitin for your replies , i cant make it more simpler than this hope you understand (any other way to do this if not which i`ve mentioned) so sometimes i can also open my cable bandwidth for other users if i want to by adding them ?
