Adding Multiple IP's to an External Interface

L1 Bithead


We have 30 External IP addresses, what's the recommended method of adding more than one IP to an interface?



L4 Transporter


You can add another ip address on your external interface with a /32 mask under IPv4 option.


Or you can use the addresses in your nat with translated packet with source address translation with address type as translated address and add the ip address.

Alternatively You can configure your layer3 interface as untagged subinterface  and add ip addresses as subinterface(/32).This way you can configure each ip as different virtual interfaces.
