Linksys EA4500 Settings and Heat problem [ Edited ]

[Warlord1981]

But i thought the DHCP disabling on the modem was supposed to prevent having double DHCP servers on the network (modem+router). So i leave DHCP be and just change NAT and bridge on modem?

Thing is, Unfortunately i cannot find any settings of  Disabling NAT or setting Bridge mode on the modem's web interface, neither does it say anything about it on the manual.. :/ The only option available is disabling DHCP..

I've reset both modem+router right now.. now what?

Could it be that the ISP has disabled this feature of the modem? (i remind you the modem is Hitron BVW-3653 and here is the manual http://www.lumieretv.com/assets/mainmenu/94/docs/Modem%20Hitron.pdf - As you can see it doesnt mention anything about bridging)

If you have reset the EA4500 to factory defaults, then all you need to do is this.

1. Go in to your modems GUI and go to the DMZ on the modem.
2. On the modem DMZ, enter 192.168.1.1 as the DMZ address.
3. Connect the Ethernet cable to your EA4500's Internet port.
4. You're done.

Whatever you do, do not disable nat on ea4500 or disable Spi firewall.

Hi Warlord,

I can see that you've done a lot of changes on the router. For this one, things shouldn't be too complicated. You have a cable modem and there is no issue with double Natting here. Let me go back to the initial post you've made. For the internet connection type it should be Automatic Configuration DHCP. Network Mode should be mixed so that everything would be able to connect. If you set it to N only, only N devices would connect. If G only, only G devices would connect. It should be mixed so whatever type of wireless device you have would connect. It would not run on B speed if set to Mixed. For the IPV6, no need to worry about that. Just leave it on default settings. No need to bridge the modem or router. I apologize if I mentioned to set the modem to bridged mode on my previous posts. I just realized you have a Cable modem. To be simple run the CD to your computer and it would do everything for you.

thx all of you for this great help!

So i dont touch anything on the modem and leave router to Auto-DHCP (settings i had from the beginning)?

I dont even mess with DMZ on the modem, like jlbjlb states?

Yup, exactly!

And then see if you get any nat errors using the connectivity test.

The ultimate goal is to not have any nat errors, while at the same time, keeping you network secure.  How you go about doing that is up to you. 

If you can run the cd and it sets it up automaticly and you don't have any problems.....then you're all set.  

And you may not mind nat errors (if you get them).  But some people do.

Guyz what is the difference between setting static routing (NAT) and making DHCP reservations?

Static routing is like telling your router to use a specific router regardless of the network traffic, distance, and bandwidth. This is used for a network setup that has more than one router that is on different IP ranges or segment. Technically, routers are designed for dynamic routing but there should be an option to setup routing on them.

DHCP reservation is reserving the IP address of a specific device that's part or connected to your network on the setup page of the router. Mostly it's found under the setup tab. DHCP reservation is used specially if you have enabled port forwarding on the router for a specific device to work. In order for you not to lose the IP address of that device after a reboot of the router, you reserve it's IP address on the router itself.

Thank you.

Therefore in my case (cable modem/router+EA4500) what do i do regarding NAT?

I've already setup DHCP.

Everything should be okay. NAT/SPI firewall on your router should stay enabled.
