Hy!
I try to make a Firewall. There are two networks. (one is 10.2.x.x/19, the other one is 10.2.22.x/19) I want that the 10.2.22.x can get trough the 10.2.x.x ^^^^^^^^^^^ This is not a valid network address. The netmask must at least be /24. And even the 10.2.x.x is not unique for a /19 netmask. Are you sure that /19 is correct?
Please post the correct networks. Another hint: If the big network is a 10.2.0.0/16, you can't have another network beginning with 10.2.
HTH, Ingo
networt to the internet, the 10.2.22.x must also access certain servers in the 10.2.x.x network.
Syntax: 0.0.0.0/0 = all ip's 1.0.0.0/8 = 1.0.0.0 - 1.255.255.255 1.2.0.0/16 = 1.2.0.0 - 1.2.255.255 1.2.3.0/24 = 1.2.3.0 - 1.2.3.255 1.2.3.0/25 = 1.2.3.0 - 1.2.3.127 /x, where x = 32-y and y is the size in bits, that are allowed. 32 - 25 = 7 bit = 127 Philippe
