Hi all.
I want to ask a general question about PPPoE usage.
Is it generally better when you have xDSL and handle the connection through mikrotik with PPPoE? Does it add any additional load?
Also, another thing. In my setup, i have my main connection that goes through 2 wifi nodes that ends up to the facility. xDSL router is located in the first end and the mikrotik router in the far end.Im using PPPoE over this wifi link. Is my PPPoE setup producing problems by design? should i just leave xDSL modem do all the job and just pass internet access to the mikrotik router?
Setup chart:
xDSL<---->Wi-Fi1 Link to mountain<----->Wi-Fi2 mountain to facility<---->Mikrotik
Link is stable at 50Mbps rx/tx without any packet loss.
Any advices appreciated
Thanks in advance
Every time in such cases I recommend to put modem in bridge mode and let mikrotik handle the pppoe. There are two advantages at place, first you have only one NAT node, and secondly the processing power of routerboard is far better than that of a modem.
PPPoE is senstive to the wireless, meaning any kind of drop in wireless connection could cause pppoe to drop and recconect, so you would need a pretty stable wireless connection.
As far as it’s been online through the link there have been no PPPoE drops.Meaning its running for 5 months now.
They main issue is a problem i have with sip trunking communications to my pbx. Ive been struggling to deal with some voice loss every ~10 minutes.
While the wireless link has a stable ~40Mbps udp bandwidth without loss.(TCP test goes 100+Mbps tranceive)
If you are not noticing any drop in pppoe connection while it is configured on the mikrotik (after the wireless link) than your wireless link is pretty good.
About the voice drops, those are very sensitive to latency and more to jitter. You need to monitor them and configure some QOS to optimize for that purpose. There got to be lot of topics in this forum about optimizing your router for pbx.
Thing is i have already set up QoS queues etc, but the problem is not the traffic it self.Intranetworking bandwidth usage is low.
The annoying thing is that i need just 300kbps/300kbps for that sip trunk and it has so much voice loss.
by the way i changed for testing purposes the pppoe and let the ISP’s modem to handle the connection. I just wait and see within the day.
Plus a sample ping to internet gateway(From CRS125-24G-Facility to >> City access modem)
Try pinging to internet, that’s where you’ll have a worse jitter. Also, moving pppoe to mikrotik will help with that, modems CPU are not ideal, while the routerboard will definitely handle it better.
