Simple balancing doesn't work
Good morning community, I have to configure, for my work, a F5 VE. So, I download F5 VE 13.1.4 in my lab @home and install it on VMWare to make practice and understand the F5 basics. What I did is configure internal and external network VPN and assign related IP. Then Pool/Nodes and a Virtual Server listening on port 5000. Everything looks good: From F5 I can reach both nodes, even with a simple telnet on port 5000. From external network I can reach external F5 interface. The problem is that F5 doesn't route connection to the pool. This is my network topology: As I wrote, external network can reach VSERVER at 10.3.0.100 on port 5000. Then from F5 I can reach nodes in the pool always on port 5000. The problem here is when from a client (external network) I try to connect to VSERVER, it seems the connection is ESTABLISHED for a while, but not forwarded to internal network. While I tried to establish a connection from a client from external network (10.3.0.128), this is what happen: 1 0.000000 10.3.0.128 → 10.3.0.100 TCP 70 61440 → 5000 [SYN] Seq=0 Win=64240 2 0.000219 10.3.0.100 → 10.3.0.128 TCP 66 5000 → 61440 [SYN, ACK] Seq=0 Ack=1 3 0.002661 10.3.0.128 → 10.3.0.100 TCP 58 61440 → 5000 [ACK] Seq=1 Ack=1 4 0.006505 10.3.0.128 → 10.2.0.129 TCP 66 61440 → 5000 [SYN] Seq=0 Win=4380 5 0.059742 10.3.0.128 → 10.3.0.100 IPA 115 unknown 0x30 6 0.059768 10.3.0.100 → 10.3.0.128 TCP 58 5000 → 61440 [ACK] Seq=1 Ack=58 7 3.003461 10.3.0.128 → 10.2.0.129 TCP 66 [TCP Retransmission] 61440 → 5000 [SYN] Seq=0 Win=4380 Len=0 MSS=1460 SACK_PERM=1 10 12.004963 10.3.0.100 → 10.3.0.128 TCP 113 5000 → 61440 [RST, ACK] Seq=1 Ack=58 11 12.004980 10.3.0.128 → 10.2.0.129 TCP 106 61440 → 5000 [RST, ACK] Seq=1 Ack=1 I'm getting crazy since configuration should be ok, could someone help me? Thank you very much, LucasAAA for Big-IQ CLI/TMSH Login
Hi, I have tried to use AAA server for authentication and authorization Big-IQ web GUI login. I configured on Big-IQ web GUI and find out that it doesn't work to authenticate user who log in into TMSH/CLI. Is there separate configuration to authenticate user through AAA server for CLI/tmsh? Thank you
How do I configure an F5 LTM VE Lab on my Laptop and drive traffic to it to generate logs?
I have successfully installed the F5 LTM VE Lab on VMWare Fusion 6, but I'm unclear how to configure it so that I can drive traffic through it from my browser (I am open to driving traffic in other ways, such as using blitz.io) with a macro. I'm unclear on the details of setting up the underlying network to do so. I have the configuration worksheet, but I'm not clear how to define the IPs and VLAN groups to achieve this objective: http://support.f5.com/content/kb/en-us/products/big-ip_ltm/manuals/product/configuration_worksheet/_jcr_content/pdfAttach/download/file.res/Configuration_Worksheet_-_BIG-IP_Local_Traffic_Manager.pdf
General Database error - Configuration - Options
Just received and starting configuring an F5 2000s. All seems to be working well, but get the following message in the GUI, when selecting System-Logs-Configuration-Options "General database error retrieving information" Trying to get some decent logging. So far the system seems to be doing minimal logging. I've done nothing at this point trying to configure remote syslog servers or anything else, so this is pretty much a factory configuration as far as logging goes. Do I have a problem that needs to go to support, or is there just something I need to do in the configuration?
Best way to trace/troubleshoot traffic between Remedy web server and app server.
I was wondering, if we have a remedy web server pool and vip and a remedy app server pool and vip, what's the best way to trace/monitor/troubleshoot traffic from the web server pool to the app server pool? This is BMC remedy 8. Thanks.HA reports tmm NOT ready
Can anyone shed some light on the following logs: I have a viprion with 2 blades. I can't configure the blades in HA Active Standby setup. Would setting up an HA with the 2 blades help eliminate this problem? I don't fully understand the deployment of our Viprion chasis having 2 blades. It has 2 F5 Big IP and all virtual servers created on the other doesn't reflect onto the other. I believe they are 2 complete different units? Not sure. Any replies would be appreciated. Thank you in advance.Is there a guide to set up a LTM VE in an internal environment only?
Hello Everyone, I'm looking into the correct way to set up a LTM VE in our QA environment so we can match our production environment more closely. The following is the main details or possible issues of the QA environment. LTM is being setup in VCenter. LTM is not the default gateway. The QA environment only has one subnet. Has anyone setup a LTM in this scenario? I know f5 gives you an error if the management VLAN is on the same subnet as the internal VLAN. If need be, we do have another network, we could use for the management and external VLANs if need be. I'm trying to keep this as simple as possible. Thanks for you help, David Williams LTM Newbie
