Last week I ditched my ISP's router/fiber with an Openvpn router behind that for a simple SFP media converter with the TP-L WDR-3600 now as main router. Got that working after a while. (made a post here afterwards to clear some things up)
Now in anticipation of higher internet speeds and generally having more devices in the house I switched that out for the TP-L C2600. Got it working mostly now, but one thing isn't: wired lan has no internet. I can ping devices wired>wlan no problem. Wlan has internet.
Now I realise that the C2600 has a different switch setup(2x CPU, eth0+eth1). This is the switch setup. (Vlan 300 is just renamed from vlan 2 , it needs to be for the fiber to work). This is the switch setup:
VLAN ID | CPU(eth0) | CPU(eth1) | LAN 1 | LAN 2 | LAN 3 | LAN4 | WAN 1 | o | t | u | u | u | u | o 300 | t | o | o | o | o | o | t
What is causing this? Can't seem to pin it down. Thanks in advance. (also disabled ipv6 when things didn't work to make things simpler, intend to activate it again later)
