asa-5512-x help with port forwarding using CLI or ASDM for mail server

[davedoggydogg]

im sure the processes is pretty simple but im going crazy, all the videos and written tutorials i find are for older versions of ASDM or dont really apply to my situation or are just flat out confusing with the forum threads backtracking. I have a ASA 5512 and am just trying to forward the ports so i can use my exchange mail server. if someone can show me the steps to forward ports using CLI or ASDM 7.1.3  it would be greatly appreciated. 

trying to forward ports: 2525  , 465,  110 , 143

puplic IP: 99.148.78.10 (not my real ip but just easier to work with)

ASA 5512 device: 10.10.50.50

Exchange mail server: 10.10.50.60

heres my conig:

Hi,

Try this NAT:-

object network obj-10.10.50.60

host 10.10.50.60

nat (inside,outside) static 99.148.78.10 service tcp 2525  2525

object network obj-10.10.50.60-1

host 10.10.50.60

nat (inside,outside) static 99.148.78.10 service tcp 465 465

object network obj-10.10.50.60-2

host 10.10.50.60

nat (inside,outside) static 99.148.78.10 service tcp 110 110

object network obj-10.10.50.60-3

host 10.10.50.60

nat (inside,outside) static 99.148.78.10 service tcp 143 143

Make sure that you have corresponding ports allowed on the ACL for the private IP.

Thanks and Regards,

thanks but i got a error,  i  tried

object network obj-10.10.50.60

host 10.10.50.60

nat (inside,outside) static 99.148.78.10 service tcp 2525  2525

 it and got the following error.

Result of the command: "nat (inside,outside) static 99.148.78.10  service tcp 2525  2525"

ERROR: Address 99.148.78.10  overlaps with outside interface address.
ERROR: NAT Policy is not downloaded

any ideas?

[davedoggydogg]

i dont know what i did, but between these extra commands i got the ports to forward : 

object network obj-10.10.50.60-1

host 10.10.50.60

nat (inside,outside) static interface service tcp 80 80

object network INSIDE
nat (inside,outside) dynamic interface

object network MULTI-SERVER
nat (inside,outside) static interface service tcp 80 80

access-list Outside_access_in extended permit tcp any object MULTI-SERVER eq 80

access-group Outside_access_in in interface Outside

object network obj-10.10.50.60-2

host 10.10.50.60

nat (inside,outside) static interface service tcp 110 110

object network INSIDE
nat (inside,outside) dynamic interface

object network MULTI-SERVER
nat (inside,outside) static interface service tcp 110 110

access-list Outside_access_in extended permit tcp any object MULTI-SERVER eq 110

access-group Outside_access_in in interface Outside

object network obj-10.10.50.60-3

host 10.10.50.60

nat (inside,outside) static interface service tcp 995 995

object network INSIDE
nat (inside,outside) dynamic interface

object network MULTI-SERVER
nat (inside,outside) static interface service tcp 995 995

access-list Outside_access_in extended permit tcp any object MULTI-SERVER eq 995

access-group Outside_access_in in interface Outside

im sure the commands/coding/scripting can be cleaned up, but this worked for me.

thanks Vibhor Amrodia for your time and help!

(note for others as reference)

the ports in red i changed accordingly ... eg 80,110,25, etc

the neon green 1 changed for every rule i added... eg: 1,2,3,4,5, etc

for others that need help with similar situation  here is a great reference website that helped me alot with setting port forwarding , internet sharing , and NAT / PAT  on the ASA 5512-x , im sure it works with the updated asa 5505 as well running 8.3+
