vpn subnet mask issue - TechRepublic 255.255.255.0 subnet mask will make x.x.x.255 the broadcast address. Whether or not the clients will actually recognize the broadcast address is a different question that may depend on the VPN Network and Subnet Helper Network and Subnet Helper MASK (DEC): .252 .248 .240 .224 .192 .128 .0 MASK (BITS): /30 /29 /28 /27 /26 /25 /24 SUBNET BITS: 2 3 4 5 6 7 8 N=Network: B=Broadcast: N B About Slash Notation

255.255.255.254??? what?? Subnet zero used

ip - Setting subnet mask to 255.255.255.255 - Network Yes, there's a problem. Your default gateway needs to be in the same subnet as your device. By setting the subnet mask to 255.255.255.255, you've told the computer that nothing else is in its subnet. A more appropriate way to do things would be to set your device IP to 10.0.0.2, your gateway to 10.0.0.1, and your subnet mask to 255.255.255.252. IP Subnet Calculator

1.5. Understanding CIDR Subnet Mask Notation

Network and Subnet Helper MASK (DEC): .252 .248 .240 .224 .192 .128 .0 MASK (BITS): /30 /29 /28 /27 /26 /25 /24 11111111 252 255 255 255 255 255 255 255 000000 11 IPv4 subnet mask is 32 bits large. In a valid subnet mask network part is represented with "1" from left side followed and ended by host part "0" - 11111111.11111111.11111111.00000000 (binary form), 255.255.255.0 (dotted-decimal form) or simply "/24" (where 24 represents that subnet network part is 24 bits long). However, the subnet mask is still 255.255.255.255. When opening the Properties dialog for the IPv4 connection on my Windows 7 RC client machine I don't see a way to specify the mask, only the IP address (static or automatic). I suspect there is a setting on the VPN server that needs changing, but I haven't seen anything relevant yet.
