NimbostratusVirtual server and http pool not accessible
Dear All,
I am new to F5 and just starting learning this technology. I purchased a training suite and practicing on F5 BIG-IP LTM v11.3 VE. On a VMware workstation, I installed 3 small linux machines as webservers (SliTaz). I also installed Ubuntu desktop which I converted to a router. My BIG-IP LTM has 3 interfaces, internal to the webservers, external to public access, and a management network. The Ubuntu desktop routes everything and I can successfully reach each and every interface, including the servers. I can also browse (http) to these webservers.
The problem:
At the beginning, I could not get the pool members up. From a post by Doodle_guy (Offline (Enabled) - The children pool member(s) are down), where he tweaked the http monitor, I managed to bring the pool up. now when I created the virtual server, I can see both the pool and its members all up. but when I try to access the virtual server from the external network, the access is failing. For the pool monitoring I am using a new http monitor (GET /\r\n\r\n) The reason I used that is the normal http did not work for me (GET /\r\n)
Any suggestions please. I am stuck at the moment and cannot proceed to follow the training.
Thank you,
Hello,
Did you add a snat configuration ? If not, try by adding the automap value to the snat setting on the Virtual Server

Dalmaren_261881Hi Yann, Thanks for your quick response. I am not sure where to activate that. I can see address translation and port translation are active in the virtual server. But I am still following the training and not to the SNAT part yet. Just by looking at the SNAT part now, I do not have any SNAT pool. Do I need a pool to be created. The external interface of the BIG-IP is on the same vmnet with the PC which is representing the public users. Could you please elaborate how I can activate the SNAT. Thank you,- Yann_Desmarest_Hi, You just need to go to your Virtual Server configuration and select the "automap" value in the "Source Address Translation" setting. That's it for snat.
- Dalmaren_261881Wow! Thanks very much Yann. It worked for me now.

- Dalmaren_261881Just to add, my virtual server config is as below: [root@BIGIP-LTM-1:Active:Standalone] config tmsh list ltm virtual Our-vServer-Web ltm virtual Our-vServer-Web { destination 192.168.1.177:http ip-protocol tcp mask 255.255.255.255 pool Our-HTTP-Pool profiles { tcp { } } source 0.0.0.0/0 vlans-disabled }
