Router 888 L3 interface missing

[tafa]

Hello, I just bought a CISCO 888 router and I am trying to configure it for a very first time. The problem is that I need the L3 port for NAT but the router shows me only the L2 ports (0-3).

 I tried this but still nothing. After 3th command shows me wrong command message so I checked with "?" and there are no commands like that.

Can you post below :

show version

show run

Also what you trying to configure ? VDSL or Ethernet delivery ?

I want to use this router as my main router but I staked in the very beginning. Can set a L3 port to take an IP from my ISP.

 Can set a L3 port to take an IP from my ISP.

we understand this, but what kind of ISP delivery, is this Ethernet or VDSL.

i would advise reading the product documentation - the Router has 1 DSL controller and 4 FastEthernet. (if you are not able to configure any FastEthernet as a layer 3 interface, then that is is Limitation of the kit. it can only be used for DSL.
