Netgear r6700ax - guest network can access my ISP router and other computers. Chrome cast not workin
https://i.imgur.com/mHe4kQu.png
I have my ISP router 192.168.50.1 which provides internet.
- My TV (192.168.50.20)
- PC1 (192.168.50.10)
are connected to it.
I bought a Netgear r6700ax; I connected the wan port to the ISP router.
It seems to create its own subnet 10.0.0.1.
I have enabled wifi and guest wifi (with not allowing access to other devices on the network) on this router.
- Phone1 is connected to wifi of the netgear (10.0.0.2)
- Phone2 is connected to the guest wifi of the netgear (10.0.0.3)
Phone1 (main wifi of netgear) can see and communicate all other devices:
- ISP router (192.168.50.1)
- TV1 (192.168.50.20)
- Phone2 (10.0.0.3)
- PC1 (192.168.50.10)
=> so all ok
I have two major issues:
1. Phone2 (guest wifi of netgear) can see and communicate:
- ISP router (192.168.50.1)
- PC1 (192.168.50.10)
=> which is not normal as guest wifi devices should NOT see any of my network especially my ISP router.
2. Phone1 (main wifi of netgear) doesn't detect chromecast (of my TV 192.168.50.20) on youtube app or any other apps.
I am not sure how to solve these issues.

That is a classic sign of "double NAT" syndrome. It happens when pile router on router.
Two routers on your network can cause headaches. For example, you can end up with local address problems. Among other things, the other router can misdirect addresses that the Netgear router usually handles, such as routerlogin.net or the usual IP address for a router, 192.168.1.1.
This explains some of the other drawbacks.
What is Double NAT? | Answer | NETGEAR Support
Unless you have specific reasons for using two routers – to create two separate networks for example – it is often easier to use just one router and then to set up the second router as a wifi access point. Netgear advises this, as does just about every site you will visit.
That has its own drawbacks:
Disabled Features on the Router when set to AP Mode | Answer | NETGEAR SupportI tried it. If I use the netgear router as AP, it works fine except guest network cannot connect to the internet...I am guessing it is because devices on the guest network is not allowed to even communicate with the ISP router for internet. (I was advised to use the wan port and use the netgear router as a router but I am getting the issues described in my first post)
