In my network I use a wireless router that assign ip address to 15 PCs through dhcp. I use an ethernet port on the router to distribute internet service to other clients . But there is a client in my network with 2 LAN cards therefore, I used an ethernet cable to tap signal directly from the router onto the second LAN card. the client is recieving transmission from the router through 2 different channels and dhcp assigned 2 consecutive ip addess to the client.

Well, the sysytem is browsing .

So what is your comment .

If your using Windows, type:

route print

under command prompt. you should see the routing table. the line that has 0.0.0.0 0.0.0.0 has the default gateway and the interface card that windows is using to connect to the net.

As far as I know windows does'nt do load balancing by default. so your probably only utilizing one LAN card for internet connection.

I think that is correct however it would be interesting to see what the routing table tells us. And test it further. As Dove said though, why would you want to do this unless one of the subnets was for hosting some services (similar to what you would probable do with a NAS/SAN and have a backend network (second interface card) to host the drives ?

Nice, any how the windows will not load balance the traffic right, then no need to do this kind of complex network isn't it?. what smurf, what you think on this.

smurf, what you think on this.

The only real reason i see to have dual network adapters is if you are connecting to a back end network for something like a SANs/SQL Clusters/etc... I cannot really see the need of it on a workstation though ! Its not likely that you would want to route to several different subnets through both interfaces though, the back end normally would be a subnet that is reserved just for hosting the NAS/SQL Cluster, etc..

Like you said, i am pretty sure that you cannot load balance by having two default gateways although i have no idea how Windows would decide which gateway to put into your routing table. Things like that do interest me as i like to know the answer to these things but at the end of the day i would think it is pretty pointless.
