perfSONAR Firewall Requirements

perfSONAR Port Requirements / Firewall Rules

perfSONAR includes many services, each of which requires one or more open ports. If you are deploying perfSONAR behind a firewall you will need to change your firewall configuration to allow the following incoming and outgoing ports. Note that in general it is not recommended to run a 10G perfSONAR server behind a firewall, as many firewalls can not do full 10G flows. Blocking outgoing connections is particularly problematic, as described in the perfSONAR FAQ. Also note that bwctl and owamp provide their own mechanisms to limit what can connect.

A sample iptables configuration for Linux is available here (and an ip6tables configuration can be found here). A script to check your firewall configuration is available here.


A summary of all required ports for perfSONAR Toolkit operation can be found on the perfSONAR website:
