Hello all,

I have recently bought a Devolo home control unit, for controlling switches, heaters, lights, etc. After plugging in to the mains and connecting a lan cable to the router you are instructed to log in to the Devolo home page and search for the unit, but it repeatedly refuses to find it. The website has limited advice but says the following; If your router/network has a firewall for outgoing connections, you have to ensure that the following ports are permitted for outgoing data traffic:

123 udp
2443 tcp
4433 tcp

I have attempted to do this on the Fritz box but I'm not certain I've got it right or whether settings need changing in Windows 10? Incidentally, the home control unit shows up fine in the Fritzbox app and also in the Devolo Windows app, but in order to use it properly it needs to connect to their website.

Any help would be very much appreciated.

Those rules refer to a firewall that blocks "outgoing connections". A router by default does not do this, and your Fritzbox certainly does not do this unless you have created firewall rules specifically to do this, meaning those rules are not needed.

If you've tried to create outbound rules that were not needed it's possible you've done this wrong which has broken things.

Ok, in front of a computer now... Reading the OP again it's clear those are outgoing connections, so I have removed my previous comments. Steve's comments above are correct.

By default your router will not block outgoing connections.

Hello both,

Thanks for the replies. I've just been talking to a friend who works with some of this stuff and he said much the same thing, so it looks like the problem lays elsewhere. I'll unplug control unit in the morning and leave it a few minutes, let it start up afresh. At least if I can rule out port issues I can look at other things. I've removed the couple of firewall permits I created in the Fritzbox, so hopefully that won't be an issue.
