Memory	Number of IPs
1G	2
2-8G	8
12-32G	16
Greater than 32G	20

Limit of Service Network Interface Card

• The number of EIP of SNAT and DNAT is less than or equal to the number of EIP which can be bound to NAT.
• One common EIP or multiple IP in the shared bandwidth can be bound to SNAT or DNAT, but the binding of one common EIP and IP of the shared bandwidth package is not supported.
• SNAT and DNAT can share one shared bandwidth, but the elastic IP cannot conflict. One elastic IP cannot be used for SNAT and DNAT simultaneously.
• A maximum of 100 port forward entries can be added to one DNAT table.
• Up to 40 entries can be added to one SNAT table.
