GL-SF1200-c52 no ethernet, wan working

Hello all,

I bought a new GL-SF1200-c52 and connected three PCs.
The GL-SF1200-c52 is connected to a Fritzbox, which is providing the internet connection.
I can access the subnet of the fritzbox and I can access the internet. But I can´t acces the other PCs which are connected with the switch of the GL-SF1200-c52. (The GL-SF1200-c52 replaces an older router, so it should not be an issue of the clients, because with the old router it´s working)

I checked all settings like VLAN and turned off the VLANS, but still not working.
Does anybody has an idea?

Please check the firewall of your other PCs.

I did. If I change the GL-SF1200 with the old router everything is working fine.

Can other PCs access the internet through the sf1200?

Yes. All PCs have Internet Access.

Sorry, I can’t think of any reason other than a PC firewall problem;

Can PCs ping each other?

Can you provide the configuration of /etc/config/network?

cat /etc/config/network

With old Router/Switch they can ping each other. If I replace it, they can´t.
