Hi, i have a little situation here i don't know how to handle, hopefully someone can give me a hint.
Our ISP gave us two public accessible IPv4 adresses, x.x.x.6 and x.x.x.7, however our public gateway is x.x.x.5. Our WAN Interface in the Firewall looks like this:
Now we are NATing Port 443 to Port1:0 and inbound mail is perfectly fine. However, our Exchange sends Mail to the outside world using the IP-Addess x.x.x.5 - this leads to some mail systems bouncing our mails, because the expect the Exchange to be found at x.x.x.6
Our ISP told me to create a SNAT rule for the exchange but i can't figure out how to do that proberly, any help is highly appreciated.
