Mikrotik behind Speedport Smart 2 T-Online German Telco

Sat May 11, 2019 12:38 pm

Hallo,

I have troubles getting my Mikrotik Routerboard to work on a VDSL2 Magenta 100 connection from t-online.
I configured the speedport smart 2 telco router as modem only then i connected my RouterBoard on Port 1 to the "speedport smart 2" router on port 4.
I removed port ether1 from the bridge and created a VLAN with VLAN ID 7 and require service tag=yes then linked the vlan7 to ether1.
Then I created a pppoe connection to over vlan7. The mikrotik webgui says connected and I also get a Public IP from telco but I cannot ping the gateway or for example google dns 8.8.8.8
/ping interface=dsl src-address=217.226.18.x 8.8.8.8 says timeout. I also checked use default route for pppoe.

Can someone maybe look at the config below? I dont know what to do next.

Okay Internet is working now the MTU und MRU was set to 1492 and service tag was set to no.
I had to wait a few minutes after I removed the use service tag option on pppoe interface dsl. It worked because something on telco side hang.
The working configuration is attached below. The Problem iam now facing is that my IPTV is very slow and hangs up every 10 seconds or so.
I checked the link speed and duplex and its set to 1gbit full duplex. I dont have any errors on the port where the TV is connected.

When the media box is started everytime a message appears: Playback not possible The quality of the network connection is bad. Please start the System Check (F104030)
When I change channel it works for a short period of time and then it hangs again after 10 seconds.

I have created a Wireshark Trace below. The Receiver Box has the ip 10.0.0.100
