Nat in Cisco IOS 9.1

Question

Good afternoon, I need to publish two mail servers
private IP
192.168.5.2
192.168.5.3
public IP
190.151.8.2
190.151.8.3
Both servers should send emails with IP 190.151.8.4
The configuration would be the next?
nat (Inside, Internet) source static 192.168.5.2 190.151.8.2
nat (Inside, Internet) source static 192.168.5.3 190.151.8.3
dynamic NAT
nat (LAN, Internet) source dynamic 192.168.5.2 190.151.8.4
nat (LAN, Internet) source dynamic 192.168.5.3 190.151.8.4

Answer 1

Marco,
You need dynamic for both of them to send emails out and static PAT to receive emails.
Dynamic
object net obj-email1
host 192.168.5.2
  nat (inside,outside) dynamic 190.151.8.4
object net obj-email2
host 192.168.5.3
  nat (inside,outside) dynamic 190.151.8.4
Static PAT
object net obj-email1-spat
host 192.168.5.2
  nat (inside,outside) static 190.151.8.2 service tcp 25 25
object net obj-email2-spat
host 192.168.5.3
  nat (inside,outside) static 190.151.8.3 service tcp 25 25
