I have a TP-Link TL-WR841N, which I connected via the WAN port to my main router, and configured the wan port as DHCP-Client. I then bridged Wi-Fi with the wan port.
All devices that are connected via the TP-Links Wi-Fi are getting their IP from the main router.
So far so good. I have 4 additional LAN-ports in the router that I'd like to use. But I want to use them as a dumb (unmanaged) switch. So connecting a cable would just forward the packages to the WAN interface. DHCP would also be handled by my main router. But I don't know how to achieve this.
LAN is 'eth0 and WAN is 'eth1'. So I thought; just set LAN to unmanaged and bridge it to eth1. But that does not work. Clients connected via cable don't receive an IP-address. Can anybody help me out here?
Here is my current network config:
config interface 'loopback' option ifname 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fd7b:fe98:8ae7::/48' config interface 'lan' option proto 'none' option type 'bridge' option ifname 'eth0 eth1' config interface 'wan' option ifname 'eth1' option proto 'dhcp' option type 'bridge' config interface 'wan6' option ifname 'eth1' option proto 'dhcpv6' option reqaddress 'try' option reqprefix 'auto' config switch option name 'switch0' option reset '1' option enable_vlan '1' config switch_vlan option device 'switch0' option vlan '1' option ports '1 2 3 4 0t'
