Samba Port Usage
From SambaWiki
When running with a firewall, several protocols/ports must be enabled to allow Samba 4 to operate as expected. These are:
- DNS: port 53 (both TCP and UDP)
- Multicast DNS: port 5353 (both TCP and UDP)
- Samba/smbd: UDP ports 137 - 138, TCP ports 139 and 445
- EPMMAP: TCP port 135
- LDAP: TCP ports 389 and 636, UDP port 389
- Kerberos: ports 88 and 464 (both TCP and UDP)
- Directory Sync: TCP port 1024
- Global Catalog: TCP port 3268
