[Solved] Can't get SMA solar inverter to communicate

Isn't the 401 code coming back from the sip server?
Yes 171.25.178.74 is proxy.ied.sma.de

yeah looks like that said go away ;) What are the details of the register? Does it list your public IP or your rfc1918 address?
There is only my public IP (WAN) I see in the package details:
-
Well then you need to get with them on why the 401

Will do that. So you're saying this can only be on their side?
I did enable siproxd but I'm not sure I did that correctly. It's disabled at the moment.

If your client was sending its rfc1918 it would be problem.
But you talked to them you can see that in the sniff and they answered back with 401 say you need to auth... You will need to get with them on why that might be, and how to auth, etc.

Ok thanks for all these details. The only thing that makes me wonder is my brother was able to register his SMA without any issues, he's not on pfsense but on a Fritz!Box.

Well it prob has built in sip ALG.. ie the thing that changes rfc1918 to wan IP.. You could always turn off the sipproxy and sniff again and see if the device is actually sending its wan on its own or its rfc1918.

No where do I see the device's private IP in the SIP packages.
A workaround would be to use another router to register the SMA but that means we won't get to know the answer to this SIP mess.. -
You shouldn't!! Did you turn off the sipproxy? Do you see it on the lan side sniff vs wan side sniff. If client is sending your wan IP without the sipproxy then you can turn that off.
Do you still get the 401?
Sniff on the lan side not your wan interface. What does the sip package show then in wireshark?

The lan sniff is talking to my neighbour's SMA (we're on the same share network, at least for now). It's probably not helping, but it shouldn't interfere if well designed.
1.51 is my neighbour's, 1.50 is mine.
-
@rosch It's night over here so no current on the device, so not helping.
I'll get back to you asap. -
You need to look INSIDE the packet for what address its trying to use.. Not the actual IPs talking..
Um sure looks like the 2nd sniff is talking to the same public IP as first.. Your saying that is your neighbors device? Maybe thats why its not registering, and saying you need to auth?

Sorry about the delay, I was away for a few days.
I have good news: it works out of the box, I was using the wrong "registering button". I used the big centered button instead of simply clicking "next". Well I didn't know, and I am sorry I made you lose some time, but I am glad it's fixed and you were all very helpful:
The center button is only to be used when you have a data logger called "SMA DATA MANAGER M".
I hope somebody else can use this info.
ps: the German SMA support got it right in their first email reply, the Belgian one did not, not even after 7 days of emails back and forth..
