linksys wireless router port forwarding

do I need to port forward at the gateway or at the router?

I need to setup port forwarding for a security DVR system. I have a linksys wrt110 router connected to the internet, and then another wrt 110 conected from port 1 on the “gateway” router to port 1 on the 2nd router. The DVR is connected to the second router. Do i set up port forwarding on the gateway router or the 2nd one. Also, I can connect to the 2nd router wirelessly, but I never can get internet (wirelessly). I get internet connected by wire, but not wireless. How do I solve this?

Thanks!

You claim the two routers are linked with Port 1 of Router1 to Port1 of Router 2. Do you mean LAN ports in both cases or do you mean LAN Port 1 of Router 1 to Router 2 WAN port?

IF YOU MEAN ROUTER1 LAN PORT TO ROUTER 2 WAN PORT:

You have a mess on your hands.

I fail to see why you have 2 routers as the second only offers to gum things up.

With the 2 router set up and the DVR behind Router 2 you will not be able to successfully port forward to DVR externally via Internet. You can port forward through Router 1 to a fixed IP address behind Router1 however this does not enable you to port forward through Router 2 to access DVR from Internet.

Now if you want to access DVR from Router 1′s LAN, and never from Internet, you can set up port forward on Router2 to the static IP address of DVR that you set up for DVR. Under this arrangement, if you are on Router 1′s LAN you can access DVR. However, I fail to see why you want to do this as you can totally eliminate Router 2, install DVR on Router 1′s LAN and you can access DVR from Router 1′s LAN directly by entering DVR’s LAN IP address.

I suggest that you do this:

1. Remove Router 2 – it does absolutely nothing of value to the LAN or anything else. Use ONLY Router1.
2. If the wireless is out of range and this is why you used the second router it is improperly configured and see below.

IF YOU MEAN ROUTER1 LAN PORT TO ROUTER 2 LAN PORT:

In this configuration, you are in fact trying to make router 2 act like a wireless access point and network switch. This can be done if you are careful and you must address these steps:

1. Assign a LAN IP address to Router 2 in the same subnet as Router 1 but with a different IP address (e.g. Router 1 has IP address 192.168.1.1, mask 255.255.255.0, make Router2 192.168.1.2 with same subnet mask; also make sure the DHCP range of Router 2 does not include 192.168.1.2 to avoid chaos).
2. Disable DHCP on Router 2 LAN side.
3. Assign DVR a static IP address that is not in Router 1 DHCP pool and not used by any other LAN device. It must be in the same subnet as Router 1 LAN.
4. Port forward to DVR from router 1.
4. DVR can be plugged into a LAN port of either Router 1 or Router 2 or to a network switch plugged into either Router1 or Router 2.
