So if I understand this right you will need to change the network on the port attached to the synology in your UniFi configuration or set the vlan tag in the synology OS, I would do the former.
doesn't the switch terminate any VLAN tagging at the port? so if I add the VLAN to the DSM configuration it doesn't receive any tagged packages and refuses them?
It sounds like you just added a second network/vlan to the existing interface which means you actually created a trunk and are getting the old network untagged and the new network with vlan tags which the synology is dropping.
with all the other devices in the IoT subnet it works with setting the VLAN on the port of the switch. If I check back on the unifi site, I found this:
'Applying a VLAN to a Switch Port
Native VLAN
The Native VLAN is the VLAN assigned to "untagged" traffic passing through a switch port. Devices physically connected to a switch port will be placed on this Native VLAN.
Tagged Networks and Trunk Ports
Ports can be configured to allow traffic from other networks. Allowing specific networks/VLANs is referred to as “tagging” them on the switch port. You can see all ports’ VLAN tags in the VLAN Viewer, found in the Ports tab.
Ports that have been tagged to allow traffic from multiple VLANs are referred to as “trunk” ports. By default, all ports on UniFi Switches are trunked to allow all VLANs. '
if I understand that in combination with your comment correctly: I set the native VLAN to 83 so everything tagged with 83 is correctly forwarded to the NAS and accepted there, stuff tagged with 1 are non native, the tag stays on and the NAS doesn't accept it?
But that would make the Synology NAS quite hard to use in any corporate setting with multiple VLANs which need to interconnect
and why does it work the other way around? while being in the default net 1 it does accept stuff from VLAN 83
Synology OS also doesn’t really support trunked ports through the UI (even though it does support a port that only uses a vlan tag) so it’s much easier to just leave them untagged.
It’s normal for a switch to strip a vlan tag when it sends a packet out, so that the endpoint doesn’t have to support vlans. Don’t worry about that. As far as the endpoint is concerned, it’s just normal subnetting.
okay that's what I thought
When it’s on the other vlan, can you even ping it? When you check the packet capture, can you see the ping and response? Where does it get dropped?
if I try to ping it it doesn't answer, the unifi logs do show that the packages have been forwarded to the subnet. If I use netcat to open a port on the other device it receives the connection request, but the NAS doesn't recognize it. Maybe I have to do some Wiresharking on a mirror port to see what exactly comes back, hoped I could get around it
I'm a bit hesitant to activate the tag in the DSM, as it states that it then needs a tagged counterpart to be reachable, and since all the other devices in this subnet aren't tagged anymore (as the switch untags the vlan at the port)
Connect a laptop into the same subnet as your Nas (so same vlan and IP range/subnet) and connect to the nas. This either eliminates the NAS or the router from the equation
did that, the NAS is easily reachable from within the subnet it's only a problem from another subnet
I also like that with the rest-server you can configure it with append-only, so even if someone wants to encrypt or delete the data they are not able to modify the existing backup
It is at the scale they are working on, there's a reason you can't get an actual person to contact you... It's too expensive to have actual people working these cases
Also, everybody started the round the same, and it was your skill, knowledge of the map etc. Which made the difference, not if you had unlocked some better scopes or weapons
For filesystems I have another gripe: if I move a file to another directory and I want to swap to the directory I just copied the stuff to I have to enter the whole path again...
I went exactly the same route as you, loved his old videos, HI. At some point I started to listen to the one with Myke (Cortex - had to look up the name) . The first few episodes where quite interesting, but it got repetitive at around episode 50 or so...
Now even the few videos he releases don't really get me anymore
And what do you do if you want to reference how fast the field moves, or why certain methods are not done anymore, but where found 'good enough' back in the days. You would still have to use the old source and cite them...
An absolute cut off doesn't teach you anything...a guidance, how to identify good sources from bad or outdated ones would be much better
