But they seem to reach the network card at least, correct? So I don't
have to start looking at the switch, should I?

No, iptables filtering is definitely disabled, just verified with
iptables:

<snip>
[bnh65367 at i04-storage2 ~]$ sudo iptables -L -n -v
Chain INPUT (policy ACCEPT 2851K packets, 511M bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 2420K packets, 157M bytes)
 pkts bytes target     prot opt in     out     source               destination
[bnh65367 at i04-storage2 ~]$
</snip>

Cheers,
Frederik
