• Thanks Bruce! It was misunderstanding between technician and I which I thought the optional module was already installed but it wasn't. After installation I could see the optional interfaces and I could configure them.
  • Yeah, I used WSM to save a configuration. I think I asked my question incorrectly. The WatchGuard M470 has optional Module (8x 1 GB Copper), But in Network Configuration I just can see 8 Gb (included) interface. How can I enable those optional interfaces?
