What IP addresses and port ranges does Skytap Cloud use?

To use Skytap Cloud and connect to your virtual machines, specific ports and IP addresses must be open through your local or corporate network. The specific requirements are listed below.

Notes

  • Generally, connections are made to or from the Skytap Cloud region where the virtual machine resides. For more information about regions, see Understanding regions.
  • If you have a private, single-tenant region, contact Skytap Support (support@skytap.com) for a list of the IP addresses and port ranges used by your region.

Traffic by connection type

Inbound traffic to Skytap Cloud

Browser access to Skytap Cloud web interface

Regardless of region, to access the Skytap web interface, you need direct access to the HTTPS/SSL port (TCP/IP port 443) at cloud.skytap.com (76.191.118.28). Test access here.

Browser access to VM desktops

Connections to a VM using the Secure Remote Access (SRA) browser client require access to port 443 (for HTTPS/SSL traffic) at one of the following addresses. Use the same region as the VM.

Shared drive, VM imports, and VM exports

FTP endpoints are used for the shared drive and for importing and exporting VMs.

  • SFTP connections use port 22.
  • Active FTP connections use port 21 to connect and port 20 for data transfer.
  • Passive FTP connections use port 21 to connect and ports 8000-9000 for data transfer.

The above ports open at one of the following addresses. Use the region where the VM is (or will be) hosted.

Attaching a public IP address to a VM opens all ports on the VM to the public Internet.

Public IP addresses may originate from one of the following IP blocks:

Published services (direct RDP, Web server, SSH server, and SMTP server)

Attaching a published service to a VM opens a single port through the Skytap Cloud VM firewall. This open port can be used to connect to a VM using services such as direct RDP, web server, SSH, and SMTP server. Traffic is port-forwarded from the higher-end port assigned using the published service to the local port of the VM. The full range of TCP/IP ports used by published services is 8193 through 32767 (inclusive). The above port range opens at one of the following addresses. Use the same region as the VM.

Outbound traffic from VMs

VM type

Information about the outbound IP address

VMs with no network modifications

By default, traffic from the VM is routed through one of several outbound IP addresses based on the region (see below).

VM outbound IP addresses by region

Outbound traffic from your virtual machine originates from these subnets:

Region IP/Subnet
US-West 76.191.118.0/29
US-Central 184.170.232.48/29
US-East 184.170.224.168/29
US-East-2 206.198.150.49/29
EMEA 185.64.245.48/29
APAC 103.27.44.80/29
AUS-Sydney 45.120.104.48/29
CAN-Toronto 184.170.236.48/29
Trial US-West 184.170.239.0/29

Outbound SMB traffic is blocked over TCP ports 137, 139, and 445.

The VM outbound IP address may change if the environment is shut down and then run again.

VMs with published services

When a VM replies to incoming traffic from a published service, the outbound traffic appears to originate from the published service IP address.

VMs with public IP addresses

When a VM replies to incoming traffic from a public IP address, the outbound traffic appears to originate from the public IP address.

Traffic by region

This section shows all IP address and port range information, organized by region.
