Thanks for the suggestion. That’s another weird part, with the firewall disabled iptables is empty:

#     iptables --list -v 
Chain INPUT (policy ACCEPT 413K packets, 1396M 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 327K packets, 23M bytes)
 pkts bytes target     prot opt in     out     source               destination
