Hi Manuel & All,

first of all thanks a lot for your sharp suggestions about how to build 
a personal m0n0 ISO CD.

Well, i've a problem with NET4501, but let me explain:

8 Public IP Address (aa.aa.aa.aa/29)
1 Lan (192.168.1.1/24) DHCP is turned off
1 DMZ (192.168.1.200/24)

on DMZ i've connect a Win machine with some services enabled like http, 
smtp, etc, it's bridge with none.

I've also added the 1:1 mappings, then the NAT rules:

1:1 mappings
External IP Internal IP Description
aa.aa.aa.aa 192.168.1.10 Web Nat

NAT rules
Proto  Ext. port range  NAT IP  Int. port range  Description
TCP 80 (HTTP) 192.168.1.10 80 (HTTP)  Web

Then the firewall rule say:

WAN interface
Proto Source Port Destination Port Frag Description
TCP * * 192.168.1.10 80 (HTTP)   NAT

seems to be correct but nothing happen when browser call http:\\aa.aa.aa.aa

if i replace all 192.168.1... with 10.0.0.1/24 it's work fine!

...but from the web server can't resolve any Internet address (his 
gateway is the base address on DMZ interface also DNS)!
...but the web server responding to aa.aa.aa.aa and 
aa.aa.aa.aa+1..+2...+3 and so on.
...but the WebGui isn't available 'cos if i've already use the Http rule 
above.

Any suggestion?

Thanks for stimulating my curiosity.
