Experiabox v10 port forwarding not working

Hi there!
It's been a few days now that I've been trying to open the ports 7 and 9 on the experiabox v10 without success.
I've followed all the possible instructions which I could find on the topic (mostly in Ducth!), however, these ports are still closed and I would really appreciate if anybody could assist!

Here below what I did in the experiabox settings interface:
1. create DHCP binding



2. open the desired ports



3. impose port forwarding



and finally when I check if these ports are open from outside my LAN (http://www.portchecktool.com/) the result is negative for both ports 7 and 9 as shown here below.



I need to open those in order to be able of remotely switching on/off my home workstation via WOL from my office location.

Help and dankjewel!

Hey boviorco, welcome to the forum! Looking at your screenshots, I think you need to make separate forwards for TCP and UDP. If I remember correctly, the combined version doesn't always work well.

Perhaps @wjb can take a look to confirm or deny my suspicion and further assist you 🙂

What are you trying to accomplish with the forwarding? What server or service is using that port?

The reason why you don't see the ports as "open" is due to the fact that there are no services listening to the ports you forwarded that would answer the message from such portchecker sites.
Normally UDP is used for Wake On LAN and UDP can't be checked at all through such sites.
Please note that you should only forward UDP port 7 or 9 (9 = standard) for WoL.
I only forward UDP port 9 to my Synology NAS running the Wake On LAN Gateway that I developed for the Synology NAS.

Application:


Port-forwarding to the IP address of my Synology NAS:


Please note that in "real life" I use a different port on the Internet like for example port 56509 meaning that the start- and end port are set to 56509 where the start- and end mapping port remain on 9.

PS. Do you have a Synology NAS and did you download the Wake On LAN Gateway last Monday around 19:00h?

Gents!
Sorry for the late reply, I've been away for a while and finally got some time to get back on the topic.
FIRST OF ALL THANK YOU ALL!
I've managed to have the WoL working by changing the port only to 9 and for UDP protocol.
Additionally - and this is my main mistake I think - I've set up the WoL tool to reach the WAN address of my router which is now taking care of forwarding all the applications to my cluster via the dedicated ports (FTP, SSH, RDP, etc..)
So, for now, everything works beautifully and I can save some energy and some machine hours
Furthermore my neighbour doesn't go crazy... ;-)
Cheers!

Please note that the IP address of the workstation will be "forgotten" by the Experia Box a short while after the workstation has been switched off. The port forwarding will than not work anymore meaning the WoL magic packet will not reach your workstation anymore.
If you face this issue, you will need to have a server that implements "subnet directed broadcasts".

Thanks for the reaction.
Is this going to happen even with the DHCP binding?
For example, the IP address of my machine hasn't changed since the last time I was working on this, which is more than a month ago..
Would you in any case suggest anything to avoid this IP refreshing from appearing?

Yes, unfortunately that is also going to happen when a DHCP binding has been defined for the machine. The IP address will not change as long as a DHCP binding has been defined for the machine or the machine reconnects within the remaining DHCP lease period. (Normally 24 hours.) The IP address is however removed from the ARP list within a few minutes. The exact time depends on the router, but it will not be a long time after which the IP address will be "forgotten".

I'm a bit confused since as I mentioned before the IP address hasn't changed and the last time the machine was switched on was more than a month ago.
All this period it's been off, therefore the reconnection has happened after quite some time..
How can I check this lease period or otherwise set it to a fixed IP?
Would it be sufficient to assign a fixed IP address to the machine?
Thanks again for the clarifications!

How can I check this lease period or otherwise set it to a fixed IP?When you have defined a DHCP binding for the machine, it means the DHCP lease time is infinite and therefore the machine will always reconnect within the remaining DHCP lease time. This is why the IP address does not change.

Would it be sufficient to assign a fixed IP address to the machine?No, unfortunately not. The ARP table is the table that contains the actual overview of connected devices providing the routing information where to find which device. This has nothing to do with the DHCP settings. By design devices that are disconnected from the network for a few minutes will be removed from the ARP table.
There is nothing you can do about that other than ensuring the network adapter remains active, even when the machine has been turned off. I doubt if this is supported by the network adapter in your workstation and if this is a Windows machine I am even convinced this will not be supported.
