the actual internet connection is working

My setup: Draytek Vigor 130 (bridge mode Vlan tag 7 for ISP) --> pfsense SG-3100 (pppoe for WAN)--> Unifi switch--> .....

maybe you have 2 instances of mpd5 running? did you try to reboot pfSense ? what version is it 2.4.5-p1 ?

[fMuhi]

Yes rebooted serveral times.

2.4.5-RELEASE-p1 (arm)
built on Tue Jun 02 17:45:24 EDT 2020
FreeBSD 11.3-STABLE

[kiokoman]

if internet is working do you see wan pppoe connected on your dashboard?
like this?

how many mpd5 do you see with

ps auxwww | grep mpd

?

[fMuhi]

Grep output:

check the content of
/var/etc/mpd_wan.conf
it should be like mine

Okay i think i know where it's coming from:

i have installed a NAT on the Draytek, to get the SNMP data. and it seems that the pppoe trys to connect it to NAT as well. And correctly there is no pppoe respond.

Any best practice ideas on how to do the communication over one physical cable properly to reach the draytek modem?

[kiokoman]

you have 2 pppoe connection defined
one running on mvneta2 and one running on mvneta0
check in the gui, you have something wrong

interface / assignement / ppp
you probably selected 2 interfaces instead of 1

[fMuhi]

@kiokoman

indeed! if i remove (just select one) on interface/port ether the NAT or the Internet is not working.

Any best practice ideas on how to do the communication over one physical cable properly to reach the draytek modem?

[kiokoman]

if you need to access the modem under Available network ports: you can assign mvneta0 as a new interface with dhcp or static ip, the modem must be configured with a different network from what you have on your lan,
like in my screenshot where I have a MODEM interface.

@kiokoman
Thanks for your support. I had a quick try, but wasn't able to get it up and running.

anyway - i'm one step further resolving this issue ;) Thanks

[kiokoman]

yes, now you have an idea of what you need to do, maybe wait for someone with a Draytek that can tell you how to configure it.
