How? Host a server, multiple static IP's - 1 DSL modem

[gauss]

I have a Mac Mini server that I would like to host from my company office. I've purchased 4 static IP addresses. I have a ZyXEL DSL modem. I also need to be able to provide Wireless access to all of our employees.

Does any know if it is possible to
1) Assign my 1st static IP to my wireless router,
2) Assign my 2nd static IP to my Mac Mini server,
3) Still provide WiFi access to my employees, and
4) Use 1 DSL modem?

I talked with tech support, and they said it was possible and that people do it, but that they didn't know how to do it. They suggested I post it to the forum. Seems like this would be a typical setup for any company that hosts an internal server that they want employees to to be able to access after-hours.

Does anyone know how to do this?

Thanks!

I don't know which ZyXel modem you have, but one that I've seen provides a way to expose the WAN segment out one of the LAN ports.

I'm presuming that the ZyXel is providing a all in one functions (modem, router, Wifi). If that router has VLAN capability, see if you can turn it on, then assign one of the existing LAN ports to the WAN side of the router. If you can do that, connect that port to your mini server and configure the server port as static IP on and address different than the address of the router portion of the ZyXel.

Make any sense? What model is the ZyXel?

You can try googing zyxel.com and dslreports.com using search terms like "full feature nat" "one-to-one" and "1:1", hopefully your modem has this feature - VLAN not needed.

I have a XyZEL P-663HN-51

@wa2ibm,
Thanks for your reply! You guessed right. The model I have is an all-in-one (modem, router, wifi).
I spent this morning learning about VLAN. My router has the ability to setup multiple WAN configurations.

If I understand you correctly, in order to utilize my different static IP's, I need to setup 2 WAN configurations. Each assigned to a different static IP that I own, correct?

While setting up each WAN configuration, there is a checkbox available called "VLAN Mux - Enable Multiple Protocols Over a Single PVC". I assume that this is an option to allow a VLAN, correct?
When I check the box, another option appears that allows me to assign an 802.1Q VLAN ID for the WAN configuration. Valid numbers are 0-4094. Correct me if I'm wrong, but this is a number that I can choose, and it is used to distinguish the VLAN's?

However, if I check the "VLAN Mux -..." option for my WAN configurations, my internet doesn't work for all devices connected to my WiFi. It only works if the VLAN Mux option is unchecked. Is there something else I need to do when I check the "VLAN Mux" option? Or should there be a different way to get VLAN working for this router?

(I've tried a lot more than this, but I figure this is the best place to start)

Thanks for your reply! I went to all the links you provided and read through them. The functionality described in those links is not on my current router. I searched my router manual for things like "1:1" or "one to one" and it came up with nothing.

My NAT table provides options for port forwarding, but not the IP address forwarding described in the links you provided.
Here's the instructions from the NAT table page:
"Virtual Server allows you to direct incoming traffic from WAN side (identified by Protocol and External port) to the Internal server with private IP address on the LAN side. The Internal port is required only if the external port needs to be converted to a different port number used by the server on the LAN side. A maximum 32 entries can be configured"

These are the columns in my NAT table that I can edit:
Server IP Address | External Port Start | External Port End | Protocol | Internal Port Start | Internal Port End | Remove IP Address"
Any other thoughts? Maybe there is something I missed?
