Re: Raspberry Pi host two wifi networks and all clients able to communicate (ethernet, wifi1 & wifi2)

You can't bridge wifi clients. Verboten by the WiFi consortium.
IIRC Avahi has a repeater mode, perhaps that can help in the present case. No idea how well that works.

Pihole is a DNS server. Something is probably wrong with the stock configuration for name resolution now.

Re: Internet radio fails to connect to mobile hotspot

Remove the static IP address definition from /etc/dhcpcd.conf
Let the address be given via DHCP by the ISP box in your LAN or in the phone.

(It might be possible to keep the static IP definition for the LAN only by specifying the “ssid” keyword in dhcpcd. I don’t see the advantage, though.)

Re: Network Bridge not assigning IP to clients

eth0 has a public IP address. I imagine your Pi has its firewall up?
If DHCP is not going through I would suspect the firewall.

I suggest you cut Internet access for a while, shutdown the firewall and see if clients can get a lease in this case.

Find the doc for your router, check the forum of your ISP, look around for an example from a user that has the same router.

Forget masquerading. If from inside your LAN, Internet works, masquerading works. The concern is port forwarding.

You need ‘masquerading’ set on your router, if it supports it.
I think the OP in concerned with traffic in the other direction.
You can be pretty sure an ISP router supports masquerading.

Re: Port forwarding for owncloud

Are you trying to access your external IP address from inside your own network? That doesn’t work usually. The router sees a request to somewhere, turns out somewhere is its own IP address, and traffic should be sent back inside the LAN (port forward)... Try from a WiFi hotspot, or through a phone d...

It could be one mount for the device, and one for each partition.
