    Hi folks,

    we recently updated one of our foreign unix agent from version 10 to 12.3. This agent was connected via VPN and therefor used the agents NAT mechanism you find in the agents .ini file. Here's an example:

    [HOSTS]
    ; 
    ; Overwrite IP destination in case of IP NATing problems (e.g. firewalls)
    ; <Agent name>=<dns name> or
    ; <Agent name>=<ip address>
    EXAMPLEAGNT             = 172.23.43.21

    Since we updated to 12.3 this does not work anymore. We get the following error message when launching a filetransfer:

    20191024/104006.439 - U02000348 Connection to '10.23.23.23:2300(ID=4)' initiated.
    20191024/104006.440 - U02002036 Could not receive anything from partner '*ID4'. Error code '113(No route to host),S(11(ID=4))'.

    It may or may not play a role here, but the IP address in the log is the wrong address. And by wrong I mean the one the host has in the target network which is not routable. I tested with 3 unix clients and a windows client. Looks like Windows clients work, unix not so much. I also tried rebuilding the agents .ini file from scratch (cause I first copied it from the original version 10 agent) with no effect.

    Anyone else having trouble with Unix agents version 12.3 and NAT? It may also effect other versions and platforms of the agent as I only did a short test on windows.

    Regards, Matthias

    Hi Matthias,

    I guess this is a bug which is fixed in 12.3 SP1 which was released today. In the actual Bug-Fixes document I found the following entry:

    A bug has been fixed where the Unix Agent did not use the host-ip associations defined in the HOSTS section of the ini file for file transfers

    Best regards,
    Tim
