Using source address affinity persistence, but exluding certain IP addresses
Hi, I would like to use source address affinity persistence, except for a few known IP addresses for which I do not want to use any session persistence at all (for stress testing the cluster, etc). Can I configure this without having to re-implement source address affinity persistence with an iRule?
Virtual Sever Subnet
Hi, I have a subnet of /25 rang for selecting VIP's, So now my question is can I use all 128 IP's (0 - 127 ) for creating Virtual server or only 126 IP's excluding Network ID & Broadcast address. I am assuming each virtual server is /32 and all IP's can be used from the subnet. Please correct me If I am wrong. Regards, Praveen

Client receive socket error
Hi all, we have just finish the F5 VE setup and starting with the 1st tesing and we encounter socket error on the client side We were able to telnet the VS IP & Port from the client. I have capture the tcpdump between client to F5 and trying to understand the handshake part.. would anyone be able to advise ?

Hi, I'm trying to setup Npath routing by the book: http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm_implementation/sol_npath.html However there are some issues and doubts about this configuration. First of all, everything is on the same network: Client IP: 10.233.203.222 Load Balancer F5 Big-IP (version 10.2.1) Virtual IP: 10.233.203.218 Pool members: 10.233.203.216 and 10.233.203.217 Route table in each pool member: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.233.203.129 0.0.0.0 UG 0 0 0 eth0 10.233.203.0 * 255.255.255.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 1002 0 0 eth0 As described in documentation I added Virtual Server IP in loopback interface using the following command: ip addr add 10.233.203.218 label lo:0 dev lo scope global I'm not a network specialist but I would like to understand the flow between request and response using Npath. Some doubts: - What's the role of VIP in loopback interface? - Why even LB down I'm able to ping 10.233.203.218 (VIP) from outside? Is it not supposed loopback does not accept traffic from outside? - Because everything is on the same network make sense to use Npath? - Even with Npath how can I control the outbound traffic if node, LB and server are in the same network: 10.233.203.X? I do not understand well the entire flow: CLIENT -> LB -> SERVER1 OR SERVER2 -> LB -> CLIENT or using Npath: CLIENT -> LB -> SERVER1 or SERVER 2-> CLIENT Thanks for you support MacHas anyone ever setup the Panopto Lecture Cast application with the LTM?
We are attempting to setup the Panopto (http://www.panopto.com/) application in out dev/test area. I am familiar with setting up the normal web server but I am not familiar with setting up the Live Streaming/Real Time Streaming virtual servers. I am currently load balancing all of the HTTP/HTTPS traffic but none of the streaming media traffic. Can anyone give me a best practices for setting up the F5 LTM (v11.4) to support streaming with Microsoft streaming media services? The vendor support for the application stated they had "very few" clients doing this and they don't have much information on the setup. Our application servers do not use the F5 as their DFG. So we will have to SNAT everything. Ports in use by the application: Port 80 - Web traffic Port 8080 - Alternate Web traffic. Required for viewing recorded content. Port 1755 - Live Streaming/Broadcast Port 554 - Real Time Streaming Content (RTSP) Port 443 - SSL (optional) Basic application diagrams from the vendor: http://support.panopto.com/documentation/admin-and-setup/how-panopto-works/panopto-deployed/panopto-server-architecture-lan-0 http://support.panopto.com/documentation/admin-and-setup/how-panopto-works/panopto-hosted/panopto-hosted-architecture Any and all help is appreciated. Thank you, Adam
Deploying LTM and integrating with BGP
Hi all I have a client who has 2x LTM. They want to deploy one per DC. I have two concerns: One: the hearthbeat that indicates and facilitate the failover is communicated over layer 2; does this mean that the two LTMs cannot sync configs and be deployed in a HA active/passive scenario? Two: if a backend server goes down in DC one, can the LTM route the traffic to the mirror server is DC2? I guess this links into the first question in terms of the two devices having visibility of what the other one is doing? The easy option is for the client to buy 2x advanced routing license and 2x GTM add-on but I am curious to know if there is a work around i.e. not buying any additional software licenses or just buying the advanced routing license. Any help you can offer to assist with this deployment would be greatly apprecaited. BR Adel
