DHCP relay server and disconnections

Hi all.
I'm testing to install an externa dhcp form my two mikrotik pppoe servers.
My question is: how does the external dhcp server know that a pppoe user has logged out and then the ip address must be released?
The relay send also this information to the dhcp server?

Thanks.

The problem is that I cannot take the result of speedtest because I must sum also the traffic the user make during the speedtest to have an accurate result.
Does someone have an hint to how to do this?

better multiple pppoe server or one pppoe server?

Hi all.
I transport pppoe connections to a pppoe server using eoip tunnels.
Eoip terminates in the same machine having pppoe servers.

Is better to bridge all eoip to one pppoe server or terminate each eoip to one diferent pppoe server in a CCR multicore?

Re: v6.22 download traffic limit problems

It seems you mangle only the traffic generated from IP belonging to the PPPoE-100M-list address list.
If so, you mark only upload traffic.
Have you evauated the possibility to add a rate-limit directly to the pppoe profiles ignoring mangle and queue?
In this case queues are dinamically created.

Re: 802.11n setup

Use wireless-fp, we use it and we have no problems.
In my opinion is not a good idea to disable MCS settings below 14.
If you use channel-width=20/40mhz-Ce, be shure you have the same configuration in station and bridge and make a frequency scan where you check fi the channel 5900 and 5920 are free.

Re: 802.11n setup

1. use wireless-fp package instead of wireless
2. be shure your frequency is free (frequency scan or, better, spectral scan)
3. you ccq must be high during speed test. If not the is too noise in the site. Try to move the antenna or isolate with some shield.
