Holy cow, what kind of IPs/masks are you trying to use??
Keep it simple:
- First you choose (or use what comes in the router) a network segment, e.g. 192.168.4.x, netmask 255.255.255.0.
- The network address must use a
private IP range and the
network mask will be 255.255.255.0 or 255.255.0.0 (for simplicity).
- Next - for each computer you want to connect and the router - you select any previously unused IP within the same network segment. This means that for all used IPs the numbers (octets) where the network mask has a "255"
must be the same and where the network mask is "0" the octets
must not be the same.
Examples:
network: 192.168.4.x, mask 255.255.255.0 (CIDR: 192.168.4.0/24)
router: 192.168.4.1
1st PC: 192.168.4.11
Amiga: 192.168.4.12
Mac: 192.168.4.13
network: 192.168.x.y, mask 255.255.0.0 (CIDR: 192.168.0.0/16)
router 192.168.1.1
1st PC: 192.168.20.1
Amiga: 192.168.19.85
On each computer you'll have to set up:
- it's own unique IP address
- the very same network mask for all devices
- the default gateway (your router's IP)
As DNS server you either use your router's IP (if it has a builtin DNS proxy) or your ISP's DNS server.
Hope that helps a bit...
