This topic explains the usage of SNAT IPv6 for virtual service.

If SNAT IPv6 is used for a virtual service, the virtual service’s configuration must include a unique SNAT IPv6 address for each SE that may be used by the virtual service. For instance, if the SE group for the virtual service’s pool can be scaled out to a maximum of four SEs, the SNAT list within the virtual service configuration must contain four unique SNAT addresses.

The VIP should have:

  1. Equal number of IPv6 and IPv4 IPs in SNAT IP pool incase of Dual Stack VIP.

  2. Only IPv4 IPs in SNAT IP pool.

  3. Only IPv6 IPs in SNAT IP pool.

Advertise VIP as SNAT: If use_vip_as_snat field is set, then,

  1. Copy the vip6 to snat_ipv6 field on the primary SE incase of only vip6.

  2. Copy the vip to snat_ip field on the primary SE incase of only vip4.

  3. Copy both vip6 and vip to snat_ip6 and snat_ip field respectively incase of Dual Stack VIP.

  4. Scaleout is blocked.

You can add SNAT address for IPv4 and IPv6 by navigating to Applications > Virtual Services. You can either create a new virtual service or edit the existing one. In the Advanced tab of the Virtual Service window, you can select IPv4 or IPv6 to add the IPv4 or IPv6 addresses respectively. If you want to add both IPv4 and IPv6 addresses, then click Both option and provide the necessary details.
