* Check whether the gateway responds to pings while using the working direct cable connection (maybe it's configured to ignore icmp requests, which is dumb but happens)
* Monitor "dmesg -w" for errors of your following actions
* Stop wifi and stop ethernet before connecting the dock (so you dont have a route and the NIC is down in "ip a" (the value inside the "<>") also netctl-auto, ifplug, anything network management.
* Connect the dock and start the ethernet profile.
* Check "ip a; ip r" on whether you've a lease and a route.
* Ping the gateway
Either lease and route are stale, or the router is confused about your lease (you had one, don't properly deregister and get a second one but the router maintains your first one) or your NIC is filtered.

This goes a bit towards using dhclient, but you could configure dhcpcd to use the clientid instead of the duid in /etc/dhcpcd.conf - though you do get a lease and are just ghosted afterwards …
(We're obviously grasping straws at this point)
Offline
I removed dhcpcd and installed dhclient, but it does not work...
Offline
Doen't work isn't an error message, but the suggestion was actually to set dhcpcd to use the clientid.
At some point you'll have to talk to your IT - providing you a lease but not responding afterwards sounds a lot like a filter gone awry.
Offline
Okay I have to figure out how to do that and will talk again to our IT.
Thank you!
EDIT:
The IT checked the filter settings and from their point everything works fine.

I checked a lot of things with the IT, but everything should work fine.
So something on my machine must be wrong, as I can connect to the Internet just fine, when using a fresh arch boot USB...
Last week at some point the connection was working for 1 day and I really don't know why

Did you try the clientid setting?
Did the IT mention updates to the dhcp server?

No they there were no updates to the dhcp.
Yes, but still no connection.

Let's see whether we can sudo-fix that and also whether you can at least send broadcasts
sudo tracepath 8.8.8.8
sudo ping -b 123.456.78.255 # ie. your IP, but the last segment is "255"
sudo nmap --script broadcast-dhcp-discover
Als let's see whether the MTU is toobig™
sudo ip link set enp2s0f0 mtu 800
ping 8.8.8.8
Offline
Should I try that with the clientid setting?
Offline
You should have tried the clientid at some point. It's irrelevant for the nmap dhcp discovery (certainly) and the broadcast (well, "should"™)
If it's down to the dhcp server / router not liking the DUID, moving to clientid should™ fix the ping w/o sudo or mtu requirements.

There's no dhcp server responding… so where does the lease come from… gnagnagnagna
Stop your network connections, check (and post)
ip a; ip r; sudo nmap --script broadcast-dhcp-discover
Connect the dock and check
ip a; ip r; sudo nmap --script broadcast-dhcp-discover
again.
Then run
dhcpcd -d
Post the output, re-check and post
ip a; ip r; sudo nmap --script broadcast-dhcp-discover
again.
Edit: and just in case, test the LTS kernel to rule out any weird driver bug.

This is bad andthe problem - whatever leases you might have had before, they were apparenly stale.
You've no carrier on the dock, ie. no active connection to any switch - like no or loose cable or a bad connection to the dock or the dock being broken etcetc.
The good part is that the situation starts to make sense again.
Since you claim to have no issues w/ ubuntu or the install iso, it's probably not the HW, so
Edit: and just in case, test the LTS kernel to rule out any weird driver bug.
Edit: in doubt also make sure that the ubuntu/install iso network connection isn't on the wlan.

I did test also the LTS kernel and the connection does not work

There's the lingering dhcpcd service and we're (*grrr*) back to square one because you immediately get a lease and an IP but afterwards you can't even detect a dhcp server - what is NUTS.
***grummelbrummelgrummelbrummelgrummelbrummelgrummelbrummelgrummelbrummel***
There's some sort of filtering and something is interfering. Let's start w/ checking whether there's a local firewall
sudo iptables -nvL
Also let's just see what other processes are running
ps aux
Do you get the same IP addresses assigned on the other systems (at least same segment, ie. the first three numbers are the same)?
Finally, please repeat the original test, but this time w/ the cable correctly attached so that we can get a meaningful output from dhcpcd

The original test output with inserted cable is given in #42.
No, it's not. You have dhcpcd running in the background when plugging the cable so we don't get any output from it.
Anyway. D'ohh.

OMG resetting these rules helped o.O
Thank you very much for your help!!!!!!
What could cause this problem?
Offline
Well, something™ is setting those rules, but it doesn't show in the "ps aux" - it'll be some udev rule or network script. Something™ related to the dock being attached.
It might be caught by the audit system and show up in your system journal ("sudo journalctl -f" follows the journal) around when you attach the dock…
Offline
Hmmm weird...I can't see anything connected to that in the journal...
After restarting I have to reset the iptables again...
Offline
I'd try w/o ifplugd (or whatever invokes that) and see wether that makes a difference.
Something™ is adding those rules and they're certainly not default - they "disable" the NIC individually but at the same time…
