NAT and PAT from Internet (External VLAN) to Internal VLAN

Hello,

 

I have a F5 BIGIP with this configuration : Internal SelfIP : 10.100.251.86/29 and Internal Floating selfIP : 10.100.251.86/29 External SelfIP (Public IP) : 41.x.x.x/29 and External Floating selfIP (Public IP) : 41.x.x.x/29

 

I have one server in the same VLAN on internal selfIP with IP : 10.100.251.81/29 and listening on port 443

 

I need to permit my users access to my internal server (10.100.251.81 on port 443) from Internet on external selfIP (Public IP : 41.x.x.x on port 10443)

 

It means that when someone type my public IP (serlfIP 41.x.x.x) and the port 10443, my F5 BIGIP should redirect the user to my internal server (selfIP 10.100.251.81) on port 443.

 

Thanks for your help.

    This should work straight out-of-the-box. Create a standard virtual server that listens on the external vlan. Attach a pool with as pool member the server on the internal network. Make sure both address and port translation are enabled on the virtual server.
