Hi skunks,<br><br>Picture this scenario: A linux firewall with eth0 facing the web and eth1 facing the DMZ. eth0 has a public IP, let&#39;s say 1.2.3.4 and eth1 has 10.11.121.1<br><br>On eth1 [internal interface] I have setup a virtual interface with a public interface <a href="http://1.3.2.4/30">1.3.2.4/30</a> Then I have a CISCO router with IP <a href="http://1.3.2.5/30">1.3.2.5/30</a> All traffic to 1.3.2.5 is of course routed by my ISP to pass thru 1.3.2.4<br>

<br>Problem is, the virtual interface [1.3.2.4] is reachable from the net [I used <a href="http://ping.eu/ping">http://ping.eu/ping</a> to test], but not 1.3.2.5 <br><br>What should I do here??<br><br><br>Thanking you in advance,<br>

<br>Me<br>
