Accessing Conduit (MTCDT-LAT1-246A-US) remotely over cellular

[John Greene]

Can anyone provide guidance as to accessing an AEP Conduit (Linux 3.12.27r13/AEP v1.4.3) over AT&T? We can get to the Linux OS fine when on Ethernet (over SSH) but not sure how to handle on cellular.

Hi John

First you would need to approach AT&T and request a SIM card that supports
“mobile terminated data”. One way this is accomplished is for AT&T to
provision the SIM with a public, static IP address. Once you have an AT&T
SIM correctly provisioned with the capability to accept inbound connections
next configure the Conduit AEP to accept inbound connections over cellular
by logging in and selecting the “administration” tab then “access configuration”.
Under HTTPS enable the checkbox “via WAN”
For remote SSH access enable the checkbox “via WAN” under SSH.
Scroll to the bottom of the screen select “submit”
then select “Save & Restart”

I had a similar issue even with a public IP SIM. Seems some ISPs block remote terminated connections of specific protocols for specific IP ranges.

Unable to use HTTP config UI on MTCDT-LVW2-247A v1.4.3 via WAN static IP

Kind regards,
Albert

Thanks for the feedback, Steve. AT&T is saying they do not offer SIM cards provisioned with public static IP addresses, though. Does that sound right to you? If so and presuming Multitech has customers with AT&T Conduits who are managing those Conduits remotely, how are they doing so? If that does not sound right, though, does Multitech have a contact at AT&T we can talk to about getting our SIMs properly provisioned?

Hi John

Yes, AT&T does offer static IP’s associated with a SIM for “mobile terminate data”
You won’t get this at you local AT&T store. You need to talk with a M2M/IOT
division of AT&T that provides this service. AT&T contacts are regional, so
I can not provide a direct contact. Ours are provisioned through our
corporate account. Look at the i2gold APN definition at this link https://developer.att.com/technical-library/apns/apn-descriptions-and-characteristics
Your best bet may be to reach out to the AT&T small business solutions and
have a local rep contact you. https://www.att.com/smallbusiness/explore/internet.html

Another method to remotely monitor/manage Conduits is our free cloud based
device management solution called deviceHQ. https://www.multitech.com/brands/devicehq
