I know that this is pretty ambiguous because many factors contribute to how traffic is routed but is it expected behavior that when clients on a NATed network try to send a packet to an address outside of their subnet but on the router's wan subnet, the router will try to communicate directly with that address? Or will packets get sent to the gateway and then back to the switch and finally to the destination?
I have a setup like this:
The gateway for the router is set to 10.1.1.1
The NATed clients (there are a few) are sending traffic to 10.1.1.X, how are they getting there?
all devices have a netmask 255.255.255.0
|modem internal address:10.1.1.1|
|
|
|switch|
|
/ \
/ \
/ \
|server address: 10.1.1.x| |router external address: 10.1.1.Y|
| internal address: 10.1.2.1 |
|
|
|client address 10.1.2.X|
background:
I'm experiencing some speed issues (dsl/to the world) when I'm generating a lot of traffic internally on the 10.1.1.0 network and I suspect that the modem (which isn't equipped for this kind of traffic) could be the source of my bottleneck if all of the internal traffic is being sent through it. I haven't had much hands on experience with networking and so don't know if it's expected for a router to behave that way.
