I have a small company and we just started out. Given our size, we really can't get a dedicated network guy for now. Recently, we moved to a lease line of our own for reliability. This is the information I was provided with (the addresses mentioned here are just examples, obviously):
IP Address WAN: 188.8.131.52 SUBNET MASK : 255.255.255.252 GATEWAY : 184.108.40.206 LAN POOL IP : 220.127.116.11/ 29 START IP : 18.104.22.168 END IP : 22.214.171.124 BROADCAST IP : 126.96.36.199 SUBNET MASK : 255.255.255.248 GATEWAY :188.8.131.52
I setup my router, to basically have a NAT, which assigns all devices that connect to the router to get a
192.168.1.X IP address. The router's IP is set to the
IP Address WAN given above and the gateway/subnet mask that was provided for the WAN. Everything is fine, and all devices have internet connectivity and local networking is working just fine. This is how my setup looks like:
+-------------+ +--------+ +---------+ | Set-top box | --- | Router | --- | Devices | +-------------+ +--------+ +---------+ | +---------+ +--------- | Devices | +---------+
set-top box has only 1 ethernet cable. I have a couple of questions:
- Are the 'LAN pool ips' publically accessible (it looks to me that they are).
- Can I give one of the devices connected to my router one of these public ips? One of the device uses
192.168.1.187and we use it from external networks by setting up port-forwarding on the router.
- What is the exact distinction between the
LAN POOLand the
WAN. I am not sure I entirely understand this distinction. The last part of the IP in WAN is '70', in gateway is '69', and in the pool, the IPs are from 90-94 with 95 as broadcast. The remaining part is exactly the same for all the IP addresses. What is the significance of this?
Sorry about the long post, and thank you for helping me out!
