Firewall & VPN Considerations
- If your firewall or VPN administrative console supports traffic filtering via headers, we highly recommend adding the
pcoip-default-sg-sni
header to the allow list. This will ensure all PCoIP traffic is permitted. - Our PCoIP Connector IPs are dynamic and sourced from a large pool of public IP addresses provided by AWS. While AWS provides a list of public CIDR blocks, we strongly discourage whitelisting by IP due to frequent changes.
- Whitelisting by URL is possible. Please contact Tehama Support at support@tehama.io to request your PCoIP Connector URL address(es).
