Basic IP forwarding question

Greetings,

 

 

I have a LTM active/standby cluster running 9.1.2. On the external vlan, the subnet is 172.31.20.0/24 and the internal subnet is 172.31.80.0/24. I have some servers on the internal vlan that are not defined as nodes nor members of pools, yet I need to be able to connect to them with http, https, etc. via the external vlan.

 

 

What is the best way to set that up?

 

 

Thanks,

 

Mike
