LTM Configuration

I have an issue and a bit of confusion with the configuration. I have 2 pools and 2 virtual servers in the same vlan, now, how can I load balance this? Do I need setup a self ip an interface with vlan 2 traffic? will I also need snat to have that traffic comeback to the hosts? I guess my confusing comes in figuring out the traffic path... any help would be highly appreciated!!! I am a complete noob with this technology and spent most of the last few days learning about it.

    If you are saying you have 2 pools and 2 virtual servers in the same vlan then I am assuming that the Vlan is already created. But I am doubtful about this that you have both pools and virtual servers in the same vlan, technically it should work but it will be against the policy I guess. You need a very good answer from other experts here on the devcentral. Because usually what happens is, we create pool members and virtual servers in different subnets and then there will a seld ip for connection between two of them. It's upto you if you want to enable the SNAT or not, but as per my observation it is enabled by all the people. Please let me know if you didn't get any of this. We have other experts also who will help us here.

    You will need to create a selfIP in this particular VLAN (local-only) on each appliance as well as floating selfIP (one per traffic group) if you're using HA. Your Virtual Server configuration must have explicit SNAT automap setting enabled, otherwise there will be asymetric routing issues. Overall, this not pretty, but is possible.

    Thanks for the responses, yeah I want to keep those 2 pools in the same vlan for server vlan requirements. I was able to get them going by having a trunk port in the one of the interfaces and then tagging just that vlan. All pools are up and running now, but I came across an issue where I would like the user to type in the VIP ip or A record and redirect to a login screen in one of the nodes in the pool.... thoughts?
