I am struggling here and not sure what I need to do but think it should be fairly straight forward. I grew up on old IOS and IGS/MGS/CGS routers but have been out of the industry for quite some time so a lot of the new commands are foreign to me. Someone else set this up. I have a device on the inside of my network that needs to talk to a device on the outside of my network on TCP/17709 for management purposes through my ASA5505. What am I doing wrong? If you would, please be specific; if you say you need to add NAT or add ACL statement, I don't know so if you could spell it out, I would appreciate it. And if there is anything I don't need, feel free to make suggestions for removal. Thanks in advance.

Hi Todd,
As far as i could understand, you have a device on outside which you wish to manage from Inside.
From the configuration I do not see any interface with name 'evertek' for which nat statements are configured.
"nat (inside,evertek) source static local-network local-network destination static Anyconnect-client Anyconnect-client
nat (inside,evertek) source static local-network local-network destination static mgt_device_outside mgt_device_outside
!
nat (inside,evertek) after-auto source dynamic any interface "
I do not find them relevant anywhere.
If traffic needs to be only initiated from Inside host to outside host then you could configure dynamic nat statement or else you could create Static.
For static(for compete subnet or for host ), you could something like :
object network obj-inside-host
host <ip address of inside host>
nat (inside,myisp) static <public mapped IP in Outside subnet or use 'interface' keyword if you wish to use outside interface ip>
for dynamic, use dynamic keyword for dynamic NAT
Also if you wish to initiate traffic to this inside host from outside, then allow the traffic on myisp interface with the help of access-list.
i do see on access-list created with myisp name but could not see any access-group to apply the same on interface.
access-list myisp_in extended permit ip any4 host xxx.xxx.xxx.zzz
access-list myisp_in extended permit ip host xxx.xxx.xxx.zzz any4
I am not sure what it is. apply the same to interface.
access-group myisp_in in interface myisp
I would suggest you to go through the configuration with your network team. there might different issue.
Regards,
Akshay Rastogi

Akshay,
Thanks. I must have forgot to replace a couple of evertek's with myisp so the nat statements are correct. Also, I am my network team so this is it. Traffic needs to be initiated from outside host. It is a device from a company that they monitor. It is actually an RTK base station that supplies sub-inch correction signal to farm equipment, tractors, combines, sprayers, etc. for auto steering over the internet as they drive through the field. The farm equipment has a 3G cellular modem also. The base station, my device, also has a backup cellular modem on it so if my internet goes down, it can still provide the correction signals to the farm equipment across the internet. The outside company monitors and manages and I am notified by them when there is a network outage. I can set my DHCP server with a reservation for the device so it will always get the same IP and try your solution.

Akshary,
To simplify, I have removed all the other commands and think I should only be working with the following commands:
object service 17709
service tcp source eq 17709
object network raven_sling_mgt
host x.x.x.x
description raven_sling_mgt
object network raven_sling_base
host 172.16.100.112
description raven_sling_base
access-list evertek_access_in extended permit object 17709 any4 object evertek
access-list evertek_access_in extended permit object 17709 object evertek any4
nat (inside,evertek) source static local-network local-network destination static Anyconnect-client Anyconnect-client
nat (inside,evertek) source static raven_sling_base raven_sling_base destination static raven_sling_mgt raven_sling_mgt service 17709 17709 net-to-net
nat (inside,evertek) source static raven_sling_mgt raven_sling_mgt destination static raven_sling_base raven_sling_base service 17709 17709 net-to-net
nat (inside,evertek) after-auto source dynamic any interface
My outside interface on my asa is called evertek and has an object defined with the static IP from my ISP.
The host that needs to get in on port 17709 is defined as the object raven_sling_mgt.
The host that needs to get out on port 17709 is defined as the object raven_sling_base.
I didn't think it would be this difficult just to open a single port between 2 IP addresses. Basically, raven_sling_mgt (x.x.x.x) in Sioux Falls, SD needs to mange raven_sling_base (172.16.100.112) inside my network and it needs to be 2-way communication so mgt can initiate the communication and base can initiate a communication.
