To use 6 IP out of the 8 ?
How to use the 2 IP of network and broadcast ?
It is simple it is enough to configure them in tunnel :
The problem in the attribution of the segment it is the mask of under network thus it should be changed gold in a tunnel it is easy to put it has 255.255.255.255
ex: freebsd
on the server :
ifconfig gif2 create
ifconfig gif2 tunnel 10.1.1.1 10.1.1.2
ifconfig gif2 62.4.21.176 62.4.21.177 netmask 255.255.255.255
ifconfig gif3 create
ifconfig gif3 tunnel 10.1.1.1 10.1.1.3
ifconfig gif3 62.4.21.176 62.4.21.178 netmask 255.255.255.255
ifconfig gif3 create
ifconfig gif3 tunnel 10.1.1.1 10.1.1.3
ifconfig gif3 62.4.21.176 62.4.21.179 netmask 255.255.255.255
ifconfig gif3 create
ifconfig gif3 tunnel 10.1.1.1 10.1.1.3
ifconfig gif3 62.4.21.176 62.4.21.180 netmask 255.255.255.255
ifconfig gif3 create
ifconfig gif3 tunnel 10.1.1.1 10.1.1.3
ifconfig gif3 62.4.21.176 62.4.21.181 netmask 255.255.255.255
ifconfig gif3 create
ifconfig gif3 tunnel 10.1.1.1 10.1.1.3
ifconfig gif3 62.4.21.176 62.4.21.182 netmask 255.255.255.255
ifconfig gif3 create
ifconfig gif3 tunnel 10.1.1.1 10.1.1.3
ifconfig gif3 62.4.21.176 62.4.21.183 netmask 255.255.255.255
on one of the client :
ifconfig gif1 create
ifconfig gif1 tunnel 10.1.1.2 10.1.1.1
ifconfig gif1 62.4.21.177 62.4.21.176 netmask 255.255.255.255
