Port filtering in My Orcon
Port filtering is an extra level of security that protects you from cyber attacks and blocks specific inbound traffic with no impact on your normal browsing, streaming, or email services. You can turn it off and on at any time by logging into My Orcon and scrolling to the bottom of the home page.
We block the following ports and inbound traffic (TCP/UDP) on a network level:
20 FTP data 21 FTP data 22 SSH (Secure Shell) and file transfers 23 Telnet 25 SMTP (Sending emails) 53 DNS servers 67 DHCP Bootstrap servers 68 DHCP Bootstrap servers 80 HTTP servers 110 POP3 servers 135 Remotely managed DHCP and DNS servers 137 NetBIOS named services 138 NetBIOS datagrams 139 NetBIOS sessions 143 IMAP servers 161 SNMP 162 SNMP 443 HTTPS servers 445 SMB over IP 547 DHCPv6 servers 593 HTTP RPC remote procedures 1900 SSDP (Discovery of UPnP devices) 2049 NFS (File sharing) 5060 VoIP/SIP 5431 UPnP ports
If you have an on-site email server (business email server), web server, NAS servers, or admin acces to a remote router, you'll want to disable the port filtering and test your services again.
