Bridging wlan0 and eth interface

Networking WiFi
1

I’ve been having some WIFI issues, mainly speed not being what I’d like it to be, so I decided to move some heavy hitter devices from wireless connection to wired, but I wanted to keep them in the BLUE zone. I figured a simple bridge would suffice. I used a spare ethernet port (eth2) and bridged it with wlan0. I did that by selecting “bridge” mode for BLUE in zone configuration and then assigned both wlan0 and eth2 as “native” for that zone. After a restart the bridge seems to be created and working:

brctl show output

bridge name     bridge id               STP enabled     interfaces
blue0           8000.02501c41d748       no              eth2
                                                        wlan0

ifconfig output

Based on this it seems like it will work OK, but wired connection doesn’t work. Wireless works fine, but if I connect a client to the wired it doesn’t. One issue I see is that DHCP gives a bogus 192.168.2.127 address, which is a loopback. If i assign a static IP it appears that I can ping local addresses, but can’t ssh or access them in any way. I tried adding “bridge=blue0” in /etc/hostapd.conf, but that didn’t seem to help.

Can anyone point me in the right direction on how to bridge wlan0 and eth2 together properly?

Thanks.

I got it solved. Let me start by saying that I’m a complete idiot. I forgot that MAC filtering was on, thus any device I was adding had to have the MAC address of the ethernet port added to the rules. Disabling MAC filtering made everything work splendidly. I’ll now have to go through laborious task of adding all these MAC addresses.

A post was split to a new topic: Selected interface is not a WLAN card

Where exactly? I can’t find it in the GUI anymore :frowning:
