How to Link NetGear wireless AC-1200 router to Sonicwall 3600

Hi,

I want to link my Netgear wireless router to Sonicwall NSA3600 firewall. Our wireless users are able to ping successfully to the LAN PC's connected to firewall but the LAN PC's are unable to ping wireless users connected to the Netgear wireless router. I have one Ethernet port connected to the wireless router for internet connection. My network connection is as below:-

Sonicwall:-192.168.3.1-254

Wireless router:-192.168.1.1-254

tried below things as a workaround:-

-Disabled firewall on both machines LAN/Wireless.

-Tried disabling the DHCP in wireless router and after disabling it, i'm not able to access the router as it is been set to use manual IP and need to reset the settings in order to get the default one.

Tried adding default gateways to the LAN's PC'c and wireless PC's

None of the above mentioned workaround worked for me!!!!

Do i need to do anything in firewall to create communication in between wireless and sonicwall devices so that both networks communicates properly?

help is much appreciated!!

John's advise is about connecting Router to same subnet and disabling DHCP so actually router will become Access Point.
If you don't want to do it because you prefer keep wireless on separate subnet and has additional NAT/Firewall then don;t fallow John's advise.
Check if you have option to set ICMP packet to be allowed from WAN to LAN on your Netgear router. Sometimes routers has predefined packets filtering option and all you have to do is just enable it.

On Most Netgear routers you need to go to:
Advanced | WAN Setup | Respond to Ping on Internet Port
If you want a separate subnet (I do this as well):

Hook up the WAN port of the Netgear to a LAN port on the SonicWall.
Give the WAN setting a Static IP on the SonicWall.
Do not turn DHCP off on the Netgear.

This works as well. I have done both.
Yes to your question, you have to make your ip isolation is disabled on the router n not enabled.

If enabled computers will not be able to communicate with each other.

Hello John/Greg/Tom,
Thank you very much for your suggestions.
FYI,
Since i have two wireless routers for the wireless users in office, i have them connected to the Sonicwall 3600 via an ethernet port for internet access. If they are connected to the wireless, they are not able to brows the local LAN resources. I mean, they have few applications they use on wireless machines and when they are trying to connect to the LAN machines with that applications, they are getting request timed out errors.

Below are two of the NetGear articles i have came across, could you please check and let me know if this is going to help me?

Many thanks all for all your assistance in advance!!

Connect them precisely as I suggested in my first post here. Three steps. I do this routinely and it works fine - LAN resources and all.  This has proven to be a very reliable method for me over the years.

With respect to the articles you posts, you do not need to use static routes - at least I never do.

Take one router, do a factory reset and set it up as I suggested.
Exactly what models are your Netgear routers? And is the point for anyone connected to those wireless routers to be able to access ALL resources on the LAN? There's no need for a wireless network that is solely for guests?
Hello John,
I did the following today but there seems to be something stopping the communication.

Do the following (works every time for me):

1. Hook up a LAN port on the Netgear router to the SonicWall network.
2. Give the Netgear a Static IP on the SonicWall network.
3. Turn DHCP OFF on the Netgear.

Restart the Netgear router and it should be connected.

I took one LAN port on Netgear router to the sonicwall X3 port and configured the static IP on the sonicwall network. Now, tried pinging and still same error (Request timed out) i could see the packets are being sent to the wireless from LAN if i do the packet capture in Sonicwall and i also see the packet is reaching to the wireless host but i'm not sure why the ping doesn't works. I'm able to ping the sonicwall and all the LAN resources from wireless but not from LAN to wireless.

I have disabled Antivirus/Firewall on the wireless devices to confirm if anything is stopping the ping requests from the LAN but still i see error (Request timed out)
Do a factory reset on the Netgear. I do this routinely on different machines and it works fine.
Hello Masnrock,
Netgear AC-1200/R6220 &R6200.

It's not Mandatory that all wireless users should be able to communicate to the LAN resources. My Requirement is that, 2 of the wireless users needs their applications to communicate with WinScp server which is on Sonicwall subnet say (192.168.3.60 server IP) and they are connected to the NetGear router which has different subnet (192.168.1.1-254). Wireless users are able to ping the server (192.168.3.60) but when server is trying to ping any of the wireless devices which is on other subnet (NetGear, 192.168.1.1-254) are getting request timed out error). If i disable the DHCP on NetGear router, i'm not able to access the router as it's being chosen  for the manual IP and i don't know what IP will the Netgear router will have after disabling the DHCP.
