This article outlines the common service ports open for accessing Serversaurus shared hosting

Traffic that comes through the Serversaurus Cloud network is filtered by a number of firewalls at the network boundary.

Ingress traffic TCP, UDP and ICMP traffic is allowed on a number of port ranges. Egress traffic is not limited in any way.

Please see below for a list of common service ports that we leave open globally:

  • HTTP, HTTPS: TCP 80, 443
  • DNS: TCP & UDP 53
  • POP3: TCP 995
  • IMAP: TCP 993
  • SMTP: TCP 25
  • SSH: TCP 22, 222
  • WHM/cPanel: TCP 2083, 2086, 2096
  • ICMP: Traceroute, Ping

We recommend that you run any custom services on these ports. If this is not possible, please contact us and we can arrange exceptions on a case-by-case basis.
