  1. Rene,

    Your scenario explains forwarding traffic to port 22 for SSH, but further down in your configuration example you are using port 25 for SMTP. Any reason for the change between the scenario and the example configuration??

  2. Hi Ralph,

    That was a typo, I just changed port 25 to 22. Thanks for letting me know!

  3. Hi Taslim,

    Hmm why would you want to do this? :slight_smile: We use PAT in this example so that someone on the Internet is able to connect to a public IP address on the outside so that we can reach our DMZ servers with private IP addresses.

    Our DMZ servers can reach the Internet by using "regular" NAT.

  4. Thanks for the example. I have been working on a similar case for ip cameras. This is port forwarding for two services to one inside host.

    Part of the config works, part doesn't.

    Essentially, need port tcp 80 and port udp 37777 forwarded to the same inside host. The port 80 works, but only on the "inside", not on the outside, and packet tracer says my port 37777 is failing.

    object network CCTV-dvr                                                    
     host 10.10.15.76
    object service 37777_udp                                                   
     service udp destination eq 37777
    access-list outside-to-inside extended permit tcp any4 host 10.10.15.76 eq www                                                                        
    access-list outside-to-inside extended permit udp any4 host 10.10.15.76 eq 37777
    nat (any,outside) source static CCTV-dvr interface service 37777_udp 37777_udp  
    object network CCTV-dvr                                                    
     nat (any,outside) static interface service tcp www www
  5. in the lab you type "R2#ssh -l cisco -p 10022 192.168.2.254" could you tell me what this is?

    thank you in advance
