Netgear Nighthawk and Verizon Actiontech Gateway (router/modem) network setup.

[YizEr]

I just purchase a Netgear nighthawk r7500 and it will arrive very soon. this will be my first Wireless Router Installation. Ok I have Verizon Actiontec router/modem gateway I want the Nighthawk to be my main router and make Verizon to be a modem. Do I just insert a Ethernet cable in the wan port of Netgear Night hawk and plug that Ethernet cable in the the Verizon router Ethernet port and it will automatically do the setup? or do I need to change some setting in the Verizon router (router/modem)gateway first? Any tips for me?

That would normally work as a double nat setup, but if you want to use your actiontec as just a modem you would want to enable bridge mode - this would just put the public IP you get from your ISP on your new nighthawk wan port.

 

double nat while it will work, not optimal setup.  And you have to make sure that the network your 1st nat is using for its lan side, say 192.168.0.0/24 is different than what your 2nd nat router is using on its lan side, so use say 192.168.1.0/24

 

Then in your first router, put your 2nd routers wan IP (should be setup static) say 192.168.0.2 in the DMZ of that first router, that way you control all the port forwards and such on the 2nd router.  This can work, but you can have problems depending on what your doing, what protocols, etc.  It would be preferred to have only 1 nat, so your first device connected to your isp is bridge mode and doesn't do nat.

How I do enable bridge mode? Because I thought when plugging a router in Verizon router it would automatically go into bridge mode. So if I just let netgear do its automatic setup it will be double nat setup?

no never heard of such a thing, how would the actiontec not think your router is just another device like a PC that it should nat, etc.

 

You would have to manually put it in bridge mode, or have your isp do it.  I would prob call your isp and ask the how or if they can put it in bridge mode.

Looking through Verizon DHCP setting which is on by default and it say that if your are using an additional gateway to assign these IP addresses you will need to turn this function off. So when I connect the Ethernet cable to Verizon Lan into Netgear wan will I need to turn off the Verizon DHCP settings? Will turning off DHCP setting and wireless the Verizon turn it into modem or will this be still considered double nat setup. any thoughts on this

turning off dhcp does not turn off nat.. It just doesn't hand out what ever network your using on the lan and you have to use static..  Which if you use something else on your network to do dhcp you would need that off, if your going to double nat then sure you could turn it off and just set static.  But you could leave it on as well, if the scope is say 192.168.0.100 to 192.168.0.254 that it hands out you could set your second router wan to be 192.168.0.2 and your fine.

 

What is the exact model number of this actiontec and can look to see if see bridge mode settings anywhere..  But just call your isp and tell them you want to put it into bridge mode.

 

Do you understand what public IP and private IP (rfc1918) are and what your router is doing to allow you to talk on the internet, which rfc1918 can not?

 

private IPs are 10.x.x.x/8 192.168.x.x/16, 172.16.x.x/12 or 172.16-31.x.x

 

These addresses can not be used on the internet.  So your isp gives you say 24.13.x.x (comcast block) your router when you talk from 192.168.1.100 say to neowin.net it makes it look like you came from that 24.13.x.x address.

 

What a double nat is this

 

internet  - 24.13.x.x router 192.168.1.1 -- 192.168.1.2 router2 192.168.0.1 ---- 192.168.0.100 PC

 

So when you talk to internet your 192.168.0.100 address gets changed to 192.168.1.2, your first router says oh my client at 192.168.1.2 wants to talk to neowin, let me change its IP to 24.13.x.x

 

Now normal soho routers are doing NAPT so the source ports are changed, etc.  We can go into details if you want..  But this is not really good setup.  If you want someone on the internet to talk to your PC without you asking for the info.. You have to forward say port 80 on first router to 192.168.1.2 then on router2 forward 80 to 192.168.0.,100.  Or put your 2nd router into the dmz of router1..

 

Like I said this is not optimal setup.. You wan it to be like

 

internet 24.13.x.x router 192.168.0.1 --- 192.168.0.100 PC

I'm using Verizon Actiontec GT704WGB

 

I don't see any bridge mode setting but in utilities section, Multiple PVC, Encapsulation there's a drop down list Bridged LLC, Bridged VC-Mux. that's the only thing I see that's come close to bridge.
