This questin is for X-Cyber

Tell what do you want to know. Try to make the question more clear.

But, you have to know that ICS is not a good DHCP server. If you have a few PCs, you better try to configure them with statics IPs, you will save a lot of trouble. I always use statics IPs.

Here is how you will make that work easy.
Lets call 'X' to the internet connected PC, and the rest 'A', 'B' & 'C'

All the computer will have the subnet mask of: 255.255.255.0

The IP addresses will be:
X - 192.168.0.1
A - 192.168.0.2
B - 192.168.0.3
C - 192.168.0.4

Now, A, B & C, you will put in the gateway field this IP address: 192.168.0.1 (X IPs).

If you have static addresses for your DNS from your ISP, then put those IPs in the DNS field in A, B & C. And you can also add the X IPs, because ICS also acts as a DNS server for local hosts.

If you need anything else, just rate this answer, and ask again.

IMPORTANT: The IP for X computer you have to put it in the TCP/IP related to the network card connected to the local network, not to the Satellite Link(in case it's a Network card also)
