Resource Limit Description
Connection/user 10 You can apply for higher quota
Dedicated Tunnel/Connection 20
Direct Connect gateway/VPC 1
Local IP translation/Direct Connect gateway 100 You can apply for higher quota
Peer IP translation/Direct Connect gateway 100 You can apply for higher quota
Number of IPs for local source IP port translation/Direct Connect gateway 20 You can apply for higher quota
Local destination IP port translation/Direct Connect gateway 100 You can apply for higher quota

Notes about Direct Connect:

  • When a Direct Connect gateway is created, the contents of IP translation and IP port translation are left empty by default. In this case, neither of them takes effect.
  • Dedicated Tunnels support BPG routing and static routing.

Notes about IP translation:

  • IP address pools cannot fall within the CIDR range of the VPC in which the Direct Connect gateway resides.
  • ACL rules for multiple IP address pools cannot overlap to avoid conflicts in network address translation.
  • IPs among multiple IP address pools cannot overlap.
  • IP address pools only support single IP or consecutive IPs, and /24 IP address range of consecutive IPs should be consistent. For example, 192.168.0.1-192.168.0.6 is supported, but 192.168.0.1-192.168.1.2 not.
  • Address pools should not contain broadcasting address (255.255.255.255), Class D address (224.0.0.0-239.255.255.255), or Class E address (240.0.0.0-255.255.255.254).
  • The local source IP port translation supports a maximum of 100 IP address pools, and each of them supports a maximum of 20 ACL rules. (Submit a ticket to apply for higher quota if needed.)
  • To switch from IP translation to IP port translation, remove the original IP translation rules and refresh the page to edit IP port translation rules.

Notes about IP port translation:

  • The original IP must fall within the CIDR range of VPC in which the Direct Connect gateway resides.
  • The original IP port must be unique. In other words, an IP port in a VPC can only be mapped to one IP port.
  • The mapped IP port cannot fall within the CIDR range of the VPC.
  • The mapped IP port must be unique. In other words, multiple IP ports in a VPC cannot be mapped to one IP port.
  • Original IP or mapped IP should not be broadcasting address (255.255.255.255), Class D address (224.0.0.0-239.255.255.255), Class E address (240.0.0.0-255.255.255.254).
  • The local destination IP port translation supports a maximum of 100 IP port mappings. (Submit a ticket to apply for higher quota if needed.)
  • If both IP translation and IP port translation are configured, IP translation takes priority in case of any conflict.
