Hello,
I have some questions about SMTP over NAT. I have a case where I´m using redundant Cisco 2911 routers and I want to configure NAT for outgoing traffic from DMZ to public.
These addresses are only from main router:
Interface G0/0 (public side) I have an address 10.192.a.252 mask 255.255.255.0
Interface G0/2 (DMZ side) I have an address 172.192.a.252 mask 255.255.255.0
I have an email-application inside the DMZ which tries to send some rapports a few times per day to clients SMTP server.
This application is located in the computer which have an ip address 172.192.a.8
Clients SMTP server is located on a public side with IP address 130.10.a.b.
My client gave me an ip address which is trusted for their SMTP server. This address is 157.45.a.125.
I´m wondering how this NAT rule should be written on my access-list that I can NAT ip address from 172.192.a.8 to 157.44.a.125? Of course using SMTP port 25.
Thanks in advance

Hi helhea,
Please post your question in the main Routing forum as the ISR2911 is not considered a Small Business appliance.
Thank you!
