We are implementing a program on mobile phones that access port 2439 for syncing files from a computer within the domain. I'm new to cisco routers, and am having a hard time wrapping my head around how to set this up. I'm using an ASA 5505 with ASDM 6.2. I'm just trying to use port forwarding to access the files. Any help would be appreciated.

Can you post current ASA config and remove any public IPs for secuirty.

I'm assuming this is what you are looking for.

Your config looks fine assuming the internal machine is 10.0.0.110.
So is the port definitely TCP and are you sure there are no other ports needed for this connection ?
Jon
11-20-2013 05:46 PM
Well, I would change the next ACE due to security reasons:
enable
config t
no access-list outside_access_in extended permit tcp any any eq 2439
access-list outside_access_in extended permit tcp any interface outside eq 2439
But as Jon stated the connection should go through.
11-21-2013 10:06 AM
The computer I am trying to reach is 10.0.0.110, the server on the other hand is 10.0.0.115 Is there an issue with that? I just don't understand why this isn't working, maybe a setting I've overlooked? I have the ports open on 10.0.0.110 and a firewall exception on the server.
11-21-2013 11:50 AM
Jeremy
I'm not sure i understand. What is the difference between the computer 10.0.0.110 and the server 10.0.0.115. Which one are you trying to sync the phones with ?
Jon
11-21-2013 01:00 PM
If they are on the same subnet traffic does not even reach the ASA so I am bit confused on what you are asking

The mobile phones need to sync with a client computer @10.0.0.110. The server is 10.0.0.115. I added this info because the router seems to be set up properly yet I still cannot connect to sync the phones. I'm thinking I have something setup wrong somewhere, just not sure how to diagnose it. The phones sync fine while connected to the companies wifi using 10.0.0.110. But unreachable when I use the outside IP address. Sorry for being confusing, I was more trying to clarify the setup.
11-21-2013 01:20 PM
Jeremy
Still can't see anything wrong with your config. Is there a specific application name for the syncing of the phones ? It may be there is some issue with them using NAT.
Jon
11-21-2013 01:32 PM
It's a program called HandiFox, it's installed on the phones, and within quickbooks. It tracks inventory and sales. Supposedly it just needs port 2439 to be forwarded. They haven't had this problem before, is there any more info you guys would like to look at? Nic setting, firewall settings? My head is spinning like Linda Blair. It has to be a rookie mistake on my part somewhere.
11-22-2013 10:56 AM
After pooring over it a couple more times I realized Jumora mentioned the subnet. Finally noticed this in the log file
static (inside,outside) tcp interface 2439 10.0.0.110 2439 netmask 255.255.255.255
The subnet mask of that address is 255.255.255.0 Looks like this is the problem. Unfortunately I haven't found how to change the subnet of that forwarding. How can I correct this?
11-23-2013 07:21 PM
Oh my friend I believe that you are confused. Please call me juanmh84 through skype today or tomorrow or at my phone number that is posted on Monday after 11 am CST.
