Ok I want to put an exsisting Exchange server behind my Firewall... my Exchange server is currently recieving mail for 2 domains... now..
my Server's IP is x.x.x.67 here is what I have tried
I added a Virtual IP on the external Interface
for
x.x.x.67
255.255.255.255
I created a network Definition for the same and called it Exchange_Ext
I Also created a Definition for Exchange_INT at the IP of 192.168.10.5
I changed the IP of the Exchange Server to
192.168.10.5
I set up SNAT/DNAT to forward all packets from
Exchange_Ext>> Exchange_INT
I opened the nessicary ports as listed by microsoft http://support.microsoft.com/default.aspx?scid=kb;EN-US;q280132
from this point I could send mail but not recieve it....
does that setup sound correct? I want to use the SMTP Proxy so I can filter spam
would I need to close the SMTP port so that SMTP would not be forwarded directly from the Virtual IP x.x.x.67?
