-Make sure `OUTBOUNDINTERFACE` and `PUBLICIPADDRESS` are exported (see above).

-Select one of your kubernetes nodes that hosts restund:
-
-```
-export RESTUND01IP=<your.restund.ip>
-```

-
-Using nftables, the firewall deployed via single_hetzner_machine_installation.md should already DNAT restund traffic to the correct node (ansnode1, 192.168.122.31).
-To verify, check the NAT table status:
-
-```
-sudo nft list table nat
-```
