port forwarding with a switch

post #1 of 17
Thread Starter 
hey guys, so i have a cisco dpq-3925x (192.168.0.1)as my main router and a netgear cg3100 (192.168.0.2) (manually changed it from 192.168.0.1) being used as a switch (disabled DHPC server). so my ps3 is connected to the netgear router using a ethernet cable. so i had already port forwarded my ps3 when it was directly connected to the cisco router, so now that its connected to the netgear switch, do i have to change any settings or should it be ok?
thanks

There's no NAT in a switched environment.

If it's all Layer2 (Same exact subnet) and the PS3 still has the same IP ADDR, no need to change anything. The switch is just forwarding packets back and forth to the router.

The switch is just an access layer to the router, giving you more ports.

Now if you were trying to connect two routers to each other, it would be another story.

Edit: The Netgear looks like a router. Make sure it is not doing any routing what so ever. It needs to be in a bridged mode. Also, make sure it's firewall is disabled, plus any NAT related items. That way it will just pass layer2 traffic to the main router.

Well, the Gateway is really going to be the defining point (Not saying Subnet mask is not important, lol). As long as the Cisco router is passing out DHCP, and is the Default Gateway (router 192.168.0.1) for the traffic your PS3 is on.

Edit: Heck, the Netgear looks like a better router than the Cisco, lol.

the netgear is an old router that i had sitting around, so i disabled dhpc on it and connected it to the main cisco router. i do have my pc and ps3 connected to the netgear. im not quite sure about the nat and bridged mode stuff, sory im quite new and am just experimenting with networking. the gateway is different for both the devices, is that a problem?

For you to use your existing port forwarding, the clients need to be in the same subnet. The Cisco router will Port Forward to clients withing its 192.168.0.x subnet.

You said the Cisco was handing out DHCP, right? You probably have one of the LAN ports on the Netgear connected to a LAN port on the Cisco. Connect a computer to it and open the command promt (CMD) and type ipconfig /all Make sure 192.168.0.1 is the default gateway.

Also, just try it out with the PS3.

Edit: Also, go into the Netgear and turn off the NAT option (Really shouldn't be trying to do it anyways since nothing is connected to the WAN Coax port).

yeah, so i disabled NAT on the netgear, the DHPC is enabled on the cisco, yes there is one cable going from a cisco LAN port to a netgear LAN port. in cmd the default gateway is 192.168.0.1 and i have set the same gateway on ps3. all done thumb.gif
thanks buddy, its really appreciated
EDIT: now when i type 192.168.0.2 in chrome, it gives me an error. is this normal, this happened after i turned NAT off

No problem. You did it correctly, we were just double checking.

Have a good night, day, afternoon, morning depending on where you are. wink.gif
