I am trying to check for live updates of attack signatures in F5, but I am getting a message. In passive devices, the signature list does not display — it keeps loading and never shows the updated signatures. Has the destination or location of the signature updates changed in version 17?Distributed Cloud for App Delivery & Security for Hybrid Environments
As enterprises modernize and expand their digital services, they increasingly deploy multiple instances of the same applications across diverse infrastructure environments—such as VMware, OpenShift, and Nutanix—to support distributed teams, regional data sovereignty, redundancy, or environment-specific compliance needs. These application instances often integrate into service chains that span across clouds and data centers, introducing both scale and operational complexity. F5 Distributed Cloud provides a unified solution for secure, consistent application delivery and security across hybrid and multi-cloud environments. It enables organizations to add workloads seamlessly—whether for scaling, redundancy, or localization—without sacrificing visibility, security, or performance.
BIG-IP VE: 40G Throughput from 4x10G physical NICs
Hello F5 Community, I'm designing a BIG-IP VE deployment and need to achieve 40G throughput from 4x10G physical NICs. After extensive research (including reading K97995640), I've created this flowchart to summarize the options. Can you verify if this understanding is correct? **My Environment:** - Physical server: 4x10G NICs - ESXi 7.0 - BIG-IP VE (Performance LTM license) - Goal: Maximize throughput for data plane **Research Findings:** From F5 K97995640: "Trunking is supported on BIG-IP VE... intended to be used with SR-IOV interfaces but not with the default vmxnet3 driver.

iRule to statically assign IP to user
Hi all, We are trying to create a new rule to assign static ip to VIP users when APM sesssion is started. Our first approach is to get session.logon.last.username to a variable, create an array with login id's an ip address for each one, and then find user login in the array to get the ip address value we have: when ACCESS_SESSION_STARTED { # get user from APM session set usuario_login [ACCESS::session data get "session.logon.last.username"] # users <-> IP list array set ips_estaticas { "usr1" "XXX.XXX.XXX.XXX" "usr2" "YYY.YYY.YYY.YYY" "usrN" "ZZZ.ZZZ.ZZZ.ZZZ" } How could we look for the user in the array to get the IP? Thanks a lot AndresBuilding a Secure Application DMZ with F5 Distributed Cloud and Equinix Network Edge

Introduction The CNF architecture aligns with cloud-native principles by enabling horizontal scaling, ensuring that applications can expand seamlessly without compromising performance. It preserves the deterministic reliability essential for telecom environments, balancing scalability with the stringent demands of real-time processing. More background information about what value CNF brings to the environment, https://community.f5.com/kb/technicalarticles/from-virtual-to-cloud-native-infrastructure-evolution/342364 Telecom service providers make use of CNFs for performance optimization, Enable efficient and secure processing of N6-LAN traffic at the edge to meet the stringent requirements of 5G networks. Optimize AI-RAN deployments with dynamic scaling and enhanced security, ensuring that AI workloads are processed efficiently and securely at the edge, improving overall network performance. Deploy advanced AI applications at the edge with the confidence of carrier-grade security and traffic management, ensuring real-time processing and analytics for a variety of edge use cases. CNF Firewall Implementation Overview Let’s start with understanding how different CRs are enabled within a CNF implementation this allows CNF to achieve more optimized performance, Capex and Opex. The traditional way of inserting services to the Kubernetes is as below, Moving to a consolidated Dataplane approach saved 60% of the Kubernetes environment’s performance The F5BigFwPolicy Custom Resource (CR) applies industry-standard firewall rules to the Traffic Management Microkernel (TMM), ensuring that only connections initiated by trusted clients will be accepted. When a new F5BigFwPolicy CR configuration is applied, the firewall rules are first sent to the Application Firewall Management (AFM) Pod, where they are compiled into Binary Large Objects (BLOBs) to enhance processing performance. Once the firewall BLOB is compiled, it is sent to the TMM Proxy Pod, which begins inspecting and filtering network packets based on the defined rules. Enabling AFM within BIG-IP Controller Let’s explore how we can enable and configure CNF Firewall. Below is an overview of the steps needed to set up the environment up until the CNF CRs installations [Enabling the AFM] Enabling AFM CR within BIG-IP Controller definition global: afm: enabled: true pccd: enabled: true f5-afm: enabled: true cert-orchestrator: enabled: true afm: pccd: enabled: true image: repository: "local.registry.com" [Configuration] Example for Firewall policy settings apiVersion: "k8s.f5net.com/v1" kind: F5BigFwPolicy metadata: name: "cnf-fw-policy" namespace: "cnf-gateway" spec: rule: - name: allow-10-20-http action: "accept" logging: true servicePolicy: "service-policy1" ipProtocol: tcp source: addresses: - "2002::10:20:0:0/96" zones: - "zone1" - "zone2" destination: ports: - "80" zones: - "zone3" - "zone4" - name: allow-10-30-ftp action: "accept" logging: true ipProtocol: tcp source: addresses: - "2002::10:30:0:0/96" zones: - "zone1" - "zone2" destination: ports: - "20" - "21" zones: - "zone3" - "zone4" - name: allow-us-traffic action: "accept" logging: true source: geos: - "US:California" destination: geos: - "MX:Baja California" - "MX:Chihuahua" - name: drop-all action: "drop" logging: true ipProtocol: any source: addresses: - "::0/0" - "0.0.0.0/0" [Logging & Monitoring] CNF firewall settings allow not only local logging but also to use HSL logging to external logging destinations. apiVersion: "k8s.f5net.com/v1" kind: F5BigLogProfile metadata: name: "cnf-log-profile" namespace: "cnf-gateway" spec: name: "cnf-logs" firewall: enabled: true network: publisher: "cnf-hsl-pub" events: aclMatchAccept: true aclMatchDrop: true tcpEvents: true translationFields: true Verifying the CNF firewall settings can be done through the sidecar container kubectl exec -it deploy/f5-tmm -c debug -n cnf-gateway – bash tmctl -d blade fw_rule_stat context_type context_name ------------ ------------------------------------------ virtual cnf-gateway-cnf-fw-policy-SecureContext_vs rule_name micro_rules counter last_hit_time action ------------------------------------ ----------- ------- ------------- ------ allow-10-20-http-firewallpolicyrule 1 2 1638572860 2 allow-10-30-ftp-firewallpolicyrule 1 5 1638573270 2 Conclusion To conclude our article, we showed how CNFs with consolidated data planes help with optimizing CNF deployments.

Protocol Profiles in LTM Chains
We have serveral virtual servers to publish our services to customers in Internet. Some of them have f5-tcp-mobile as Client profile because are use from mobile APPs and the rest have f5-tcp-wan. All of them have f5-tcp-lan-optimized as Server Profile. In some scenarios there's a LTM outside that has PErformance Layer 4 Virtual Servers without TLS Decryption and pools where the nodes are virtual servers that are behind a firewall. In that case, the first Load Balancer should have client SSL Profile F5-TCP-LAN-OPTIMIZED Mobile Client (5G) -> INTERNET -> External LTM ( f5-tcp-mobile client profile) -> Internal LTMs ( Server Profile f5-tcp-lan-optimized) The question is: Should the server profile in the first LTM and thr Client Profile in the second LTM f5-tcp-lan-optimized or should the second LTMs have f5-tcp-mobile?AFM Logging Proxy Protocol Header Sent by F5 XC
Hello, We are using F5 distributed cloud XC DDOS service for our published services in proxy mode all traffic coming to F5 BIG-IP AFM sourced from XC IP ranges, at the same time XC is inserting "PROXY Protocol" version 2 header. I need your help to know how to extract "original IP" from header and send it to an external syslog server via irule or any other way. Thanks
F5 HA deployment in Azure using Azure Load Balancer
I just created an HA 90 (Active/Standby) peer for one of our customers adding an F5 to their current stand alone infrastructure in Azure. We are using a 3-NIC deployment model using the external interface for the VIPs and the Internal for our HA peering. We are also using secondary IP addresses on the external NIC which are in turn used for the VIPs on the F5. ✔ 3-NIC BIG-IP deployment (Management, Internal, External) ✔ Secondary IPs on the external NIC ✔ Those secondary IPs are mapped to BIG-IP Virtual Servers (VIPs) ✔ Internal NIC is used only for HA sync (not for traffic) For redundancy I have suggested using CFE in for failover but the customer wants to use and Azure load balancer and having the F5s as backend pool members. They do not want to use CFE. Is it possible to deploy an F5 HA pair in Azure using an Azure Load Balancer while the VIPs are using secondary NICs on the external interface? I'm afraid using an ALB would require making changes to the current VIP configurations on F5 to support a wildcard. Any other HA deployment models within Azure given the current infrastructure would also be helpful. Thank You
