Known Affected Versions:

Opened: Sep 16, 2024 Severity: 2-Critical
BIG-IP Next SPK may exhibit incorrect DNS46 address translation after changing the dnsNat46Ipv4Subnet in the F5SPKEgress Custom Resource.
Various traffic impacts may occur due to previous address translation being applied to DNS46 traffic depending on other network configuration including but not limited to: - Unroutable traffic - Duplicate IP Addresses - Dropped traffic - No traffic impact, just incorrect/undesired translation addresses
- BIG-IP Next SPK is deployed and running - F5SPKEgress Custom Resource is deployed with dnsNat46Enabled - F5SPKEgress Custom Resource is deleted and re-applied with a different dnsNat46Ipv4Subnet.
Delete the F5SPKEgress Custom Resource, scale the f5ingress pod to 0 then back to 1.
