I have an existing RB433 with 2 radio cards. ROS 5.4
wlan1 - configured as station 5.8ghz. used as backhaul. ARP=proxy-arp
wlan2 - configured as AP 2.4ghz using pppoe for some clients and masq. for others. out interface is wlan1
static route
no dhcp
This all works fine.
Backhaul--->RB433 wlan1 - masq/pppoe -wlan2--->clients

I wanted to add an RB411ah 5.8 AP at the location and connect it via the RB433 Eth1. None of the eth ports are used as yet.
I created a bridge on RB433. added eth1 and wlan1.
set bridge ARP=proxy-arp and set wlan1 back to ARP=enabled
set ip's from wlan1 to bridge and set masq out bridge-interface to wlan1

This is when the customers started getting annoyed. no internet
I played with bridge settings - use ip firewall yes..no... no internet use ip firewall for pppoe yes..no.. no internt

I'm sure it's something simple that I'm missing.. It always is!!
I disabled the bridge and set all the settings back to original to make my customers happy again.
Can anybody offer any suggestions?

why this proxy arp?

add pppoe on a interface facing towards the customer.. and wolla its ok. If pppoe server is not on same device, just add interface pointing to pppoe and customer to bridge. Dont adjust this proxy arp setting.

if you want fully l2 network.. use wds.

why this proxy arp?

http://wiki.mikrotik.com/wiki/PPPOE_Server

proxy arp is used to reply the host mac from unit with proxy-arp. If you use ppope server per interface. Proxy arp should be ok. (but still not needed) If using a sentraliced pppoe, dont use proxy-arp, as all cpe's reply from same mac (the interface with proxy arp enabled)

I cannot understand why you want to do a proxy for your arp's

Mostly because it works if you're running the pppoe server on the AP.
If you change the wan facing interface back to arp=enable traffic ceases to flow.

That works!!

The part that doesn't work is when I tried to tie in another AP to ether1.

My default setup:

pppoe server running on loopback interface bridge, arp enabled. Port added to bridge = etherXX and ether XY + a bounch of vpls. all with arp enabled. Works like a charm.

Loopback bridge..hmm


I ended up installing another RB for backhaul. Added a switch and set up the pppoe the same as all my other ones. With proxy-arp on eth port.
