Nat in Cisco IOS 9.1

[MarcoPoffal]

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

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
