Blocked Ports

Q:
What ports are blocked on Sparklight Business's high-speed internet service?

A:

Sparklight Business reserves the right to employ network management practices (e.g., to prevent the distribution of viruses or other malicious code) as well as to block the transfer of unlawful content. As such, Sparklight Business blocks ports 135, 136, 137, 138, 139 & 445. In addition, SMTP Port 25 and SSDP Port 1900 are restricted for business customers.
