Hi Team, Hope all of you are doing good. I have below issue :- We have pool of clients (set of proxy server, 1.1.1.1 - 1.1.1.6) , F5 is getting traffic from all Client IP and responding back, except for IP 1.1.1.5. From 1.1.1.5, traffic is getting initiated but its not reaching F5. We can see traffic generated from Client reaeching to firewall and then switch but not seeing same time at F5. Sniffer at firewall says that F5 is not responding for syn packet, but how F5 will reply if it is not seeing SYN packet? Please help to look into this from F5 perspective. Regards, RAQS
F5 BIG-IP LTM pool no outbound traffic
Hello, I am trying to setup a new virtual server (port 80) on F5 BIG-IP. I can ping the VIP and all its member IP. I can ping to the self IP of the F5 from the member server. Service is http and it's running normaly when I'm accessing the server directly, but it gave me a blank page if I access it using the VIP. When I check the pool statistics, it shows bits & packet IN but no bits & packets OUT. I am totally new into this BIG-IP thing, can someone please guide me as clear as possible of what I should do to get this working? Thanks in advance :)
Installing Backup
Hi All, I need to import UCS backup from an F5 VM which is running on ver15.1.2.1 to a new VM which is running on ver12.1.5.3. Is it possible or I have to do an upgrade on new VM to make the version same on both? I know that I need to take master key of the existing VM while importing the backup? What should I do about the existing license in the UCS file --> running this command will work "load sys ucs no-license" or I have to run any other to command to make this work? What other steps are need to import the UCS file successfully? How to confirm whether the complete config is imported or not? Sorry for asking so may questions, I tried searching for all these but no help. Thanks, Ashish Solanki
Azure App Services and routing,protecting with F5
Is it possible for Azure F5 LTM module to load balance or route traffic to Azure Web apps? I have web app http://xyz.azurewebapp.net and I want to route this traffic form Azure F5 LTM module www.mycompany.com. The reason for routing through F5 is to secure it and block unwanted url to be accessible by the public and also domain verification is not an option for us. Azure app gateway does this for us, want to see if F5 can do this. Any pointer is appreciated.Health Monitor for 3389 port Pool members
