This interface, which is not part of the switch, is available to routing logic just as eth0 and the vlans are. The wireless device is on a separate interface called eth1. Vlan1, is the one on which the WAN socket resides.Īnd here is more information regarding the wireless device: Vlan0, is the one on which all of the numbered (1-4) RJ45 sockets on the back belong to. Within the switch entity there are defined two VLANs - vlan0 and vlan1. You will notice the vlans don’t match but those are just representations. There is an excellent description of how networking is setup on the DD-WRT router here, here is a picture from that article: When we SSH over to a DD-WRT router we are actually not seeing the full picture. Both vlan1 and vlan2 are going through nvram get wl0_ifname ![]() So we have two physical interface: eth0 and eth1. ![]() Link/ether 82:60:9c:xx:xx:xx brd ff:ff:ff:ff:ff:ff Link/ether 98:fc:11:xx:xx:xx brd ff:ff:ff:ff:ff:ff DD-WRT Network InterfacesĬhecking out all the interfaces I see the ip link ![]() We can see that vlan2 is used as our public facing interface and br0 is used as the internal interface. There are a lot after that, but they are just empty chains. ![]() Chain INPUT (policy ACCEPT 0 packets, 0 bytes)
