I have DD-WRT on a netgear R6300V1 for my primary router. When running ifconfig in a command window on the admin tab, I saw eth0, eth1, and eth2 come up. What's the difference? Which is the main interface to the internet? What are the others? All had substantial traffic.

See the following for a general idea http://www.dd-wrt.com/wiki/index.php/Default_Configuration_Overview

Where I suspect in the case of the r6300
eth0 = physical network interface
eth1 = physical interface for 2.4 GHz
eth2 = physical interface for 5 GHz

vlan1 = virtual interface for all lan ports
vlan2 = virtual interface for wan port

br0 = bridge interface connecting vlan1, eth1, and eth2 (ex your local network ex 192.168.1.0/24)

hello all, I have a question on vlans/

right now my router is set up as vpn for lan ports and 2.4 and 5g wifi(192.168.1.1). I created a bridge for a 3rd 5g ssid for wifi on a different IP scheme (192.168.2.1). it works well. my question is there any way I can get the 3r ssid on a vlan so it is off the vpn for faster speeds. right now its brindge (br1) to (wl1.1)

thank you
