Why do you have DHCP on on .100? Don't you have DHCP server on the main router?

If you are saying that you can ping .100 from .101 and .102 clients but can't access .100 share (while you can access the same share from the same devices if they are connected directly to .100, then the only other thing I can think of now is that you check Windows firewall in case you have those networks as public, hence blocking file sharing.

On a separate note, you may clean the config a bit by commenting out the lines related to WAN in the different files.

You could also try commenting out these lines in /etc/config/network if you don't need them.

	option delegate '0'
	option stp '1'

I am accessing the share from cellphones. Mostly iPhones with VLC.

Could you please explain the function of those?

option delegate '0'
option stp '1'

I think for easier diagnosis it might be best to try from a PC.

The first line is about IPv6 tunnelling.
The sending [second] one is about spanning tree protocol, which is useful when you have possible multiple paths between two modes in the network, as it is used to avoid loops.

The first line is about IPv6 tunnelling.

I am not using IPv6. It is not being deployed by ISP yet. It is good to have it 0 or 1?

The sending one is about spanning tree protocol, which is useful when you have possible multiple paths between two modes in the network, as it is used to avoid loops.

Can you exemplify this? I've always considered this to be on.

26

I meant to type: the "second" one.

27

I've seen those definitions but I was looking for a layman's example and how to relate it to a network similar to mine and if it does not apply, how to apply it in the future (possible case).

28

If there are two possible routes between 2 nodes, then you need STP.

option delegate '0'

What about this? It is off right?
What's this for and where can I find it in Luci?
