Captain uses:
|
|
- 80 TCP for regular HTTP connections
|
|
- 443 TCP for secure HTTPS connections
|
|
- 3000 TCP for initial Captain Installation (can be blocked once Captain is attached to a domain)
|
|
- 7946 TCP/UDP for Container Network Discovery
|
|
- 4789 TCP/UDP for Container Overlay Network
|
|
- 2377 TCP/UDP for Docker swarm API
|
|
- 996 TCP for secure HTTPS connections specific to Docker Registry
|
|

Or simply disable firewall entirely. In case of an ubuntu server, run `ufw disable`.

Also, if you are using Port Mapping to allow external connections, for example from your laptop to a MySQL instance on Captain, you will have to add the corresponding port to the exclusion as well.
