Config of Generic host with multiport.

I guess the answer depends on the definition of "multiple ports". Is it a specific set of ports, or any/all ports?

If it's any/all ports, you can simply create a VIP with a wildcard port (*), disable port translation, and send to a pool that also uses wildcard ports. A request coming in to IP:1414 will get sent to the pool on port 1414, and hopefully there will be a server there listening on port 1414 to receive this.

If it's a specific set of ports, you cannot define a single VIP this way. You can allow all ports and then limit what's accepted in an iRule (blocking everything else).

On the monitor question, you'd want to use a port-agnostic monitor, like an ICMP 'ping'.

it's depending,

the best solution, if you only had a few ports to manage is to create a specific HOST / VS for each port.

That will allow you to monitor independently the differents ports/service. And to do a specific configuration for each Host if needed...

Hope it's clear.

Its a specific set of Port i.e. port 21 and 22. So I have to allow all ports for this VIP then I can assign moniter of port 21 and 22 on this VIP. Is this right? But is it feasible to allow all ports by considering security.

You really have two choices:

• Allow all ports and disable non-accepted ports via iRule or LTM policy

   

• Create two separate VIPs, one per port
