+As long as you are using the standard ports. This port rules are defined in `/etc/ufw/applications.d` (for the deb package only).

+Further explanations:
+Inbound traffic should allow following ports:
+**1090/udp** for the **lokinet-router**
+**22022/tcp** for **oxend** p2p
+**22025/tcp** for ** quorum/blink** communication
+**22021/tcp** for **storage server**: for remote clients to talk to service node
+**22020/tcp** for **storage server**: service nodes talking to other service nodes.
+
+Outgoing traffic should be allowed for all ports.
 
+If you want to run a testnet node, following ports should be open for inbound traffic:
+ports 38156, 38159/tcp for oxen-daemon
+ports 38154, 38155/tcp for oxen-storage-server
+
+Verify and double-check that UFW is working properly and all ports are set correctly:
+```
+sudo ufw status
+```
 
 Optionally, if you do not need *ipv6* connection you can delete this rules by modifying the general UFW settings.
