Hah? .5 is not broadcast address sir. Its the first ip in the subnet of 1.3.2.4/30. on lower subnet of 1.3.2.0/30 network - .0 usable = .1,.2 broadcast = .3 on subnet of 1.3.2.4/30 network = .4 usable = .5, .6 broadcast = .7 Wilson./

Hi skunks,
Picture this scenario: A linux firewall with eth0 facing the web and eth1 facing the DMZ. eth0 has a public IP, let's say 1.2.3.4 and eth1 has 10.11.121.1
On eth1 [internal interface] I have setup a virtual interface with a public interface 1.3.2.4/30 Then I have a CISCO router with IP 1.3.2.5/30 All traffic to 1.3.2.5 is of course routed by my ISP to pass thru 1.3.2.4
Problem is, the virtual interface [1.3.2.4] is reachable from the net [I used http://ping.eu/ping to test], but not 1.3.2.5
Am wondering if you could give the actual subnets. *1.3.2.4/30 is network address and 1.3.2.5/30 is first ip in subnet. * Wilson./
What should I do here??
Thanking you in advance,
Me
