traffic flow from new vlan

Hi Aaron,

 

 

Thank you for your response. I did more reading trying to make sure I understand the SNAT concept correctly. While I understand the various concepts and examples I have seen for SNATs I am having trouble translating it to what I have on my F5. So, I'll add some the specific IP address examples (some numbers changed to protect the innocent).

 

 

The F5's external VLAN is on the 10.38.92.0 subnet. Internal VLAN is 10.38.141.0. The subnet with the VM's that we are trying to load balance are on the 10.38.158.0 subnet with netmask of 255.255.254.0.

 

 

I am attempting to load balance two VM machines on the 10.38.158.0 subnet (10.38.159.xx and 10.38.159.xx). I created a pool with the above two ips in them using port 8080. We setup a virtual server with an ip address of 10.32.92.109 that points to the pool with the above two servers. Client requests to these two will also come from the 10.38.158.0 subnet. For example when I do the wget command I am coming from 10.38.159.12 to the virtual server of 10.38.92.109 and attempting to reach one of the two servers in the pool.

 

 

I believe your assessment that the two servers in the pool are routing around the F5 is correct. The default gateway on all of these VMs is 10.38.158.1. When you suggested using a SNAT pool I attempted to put the two VMs I'm trying to load balance into the SNAT pool. That didn't work. As I read more I felt like I was understanding less and less about how I should setup a SNAT pool for these two VMs. I also tried going into the Route section of the F5 and tried to setup something that would route the 10.38.158.0 subnet to the 92 subnet which didn't work.

 

 

I'm putting this info out here so you can give me some concrete suggestions and guidance about how I should setup this SNAT configuration.
