Exchange and external access

I guess I need more information on what you are trying to do.  I don't understand about the Routers built in garages or what you are trying to do with SMTP.  The exchange server is the SMTP server and you would connect to it via a client, like Outlook.  If you need remote access, then you would use RDP, TeamViewer, UltraVNC, etc. and use that interface.

So I am confused about what you are trying to do here.

I *think* they meant that the routers are built-in, inside garages (so presumably hard to access), rather than having been assembled in a garage.

I could be wrong, and I don't really understand the question either.

Yes, the router is in the garage and gets internet via 4G.
The router has no connection to my network.

The routers can send alerts and warnings via email.
But on the settings I have to insert a SMTP server.

How can I solve it , maybe via relay or something else ?

Hi,

If the router has no connection to your network, then what is it doing?

Isn't the purpose of a router to connect one network to another?

Sorry, probably me, but I am still confused.

Thanks,

Alan.

This router has connection to 4G network, not my corporate network.
The has to send alarms and warnings.

Okay, but it must be connected to some network at you end, else it won't actually have any purpose?

For example, you might have an alarm system on your network, and that is connected to the router (LAN side) and the router is connected to your 4G provider (WAN side).

Alan.

the router has no LAN side.
The router just has WAN connection to 4G provider, not connected to us.
There is no direct connection possible because of poor infrastructure.

I have thought about VPN over 4G but this is too complicated when we have to connect over 200 routers.
These are industrial routers to connect many sensors like fire, water, gas, door windows etc.

Is there no way to use my exchange server in my corporate LAN ? Like RELAY ?

Hi,

I'm just not understanding what you want to connect?

You talk about sensors, but are they not connected to the router (LAN side)?

If not, then what are the sensors connected to?

Thanks,

Alan.

yes the sensors are connector to the router.

Okay, so is it the sensors that you want to be able to send messages out using smtp?

the SMTP configuration has to be done on the router. Just here I have the settings like SMTP SERVER....
So, my SMTP server is in the datacenter.

What can I do ?

Hi,

I would have thought the devices would need to be setup to connect to the smtp server, but regardless, what hostname or IP address is your smtp server in the data centre on?

Alan.

Hi,

If you don't answer our questions, it is difficult to help you.

My last question was about what hostname or IP address is your smtp server in the data centre on.  This will directly impact on what you need to put into the devices and / or routers to make it work.

Alan.

With all respect, I have explained the situation several times.

There is an industry router not connected to our network somewhere in a garage.
There is no landline or whatever just 3G network.
On the router I can enter a smtp serber to send emails.

But my emailserver is in my network and not connected to the router.
What can I do to send emails from this external device ?

Any ideas ?

Hi Eprs,

How many posts did it take before you told us what was on the LAN side of the router(s)?  You kept insisting there was nothing, then changed your story and said it was sensors.

Regardless, as I posted above, twice already, do you know the hostname or IP address of your SMTP server that is in the data centre?

Thanks,

Alan.

yes of course I know the address of my smtp server in my LAN.

The LAN side on the router is not relevant, there is no LAN, just WAN.
here is the model : Phoenix Contact Router 2702528 Typ TC ROUTER 3002T-4G

Hi Eprs,

Let's back up.

What is the purpose of the router?  What is it doing?

Alan.

Here is the link about the 4G router.

The 4G router is located in a garage.
When there is fire or a door will be opend, we should get an email.
Thats it.

The router is conected to 4G network, NOT TO MY LAN.

Hi Eprs,

Are the sensors connected to the router, and the router then has a 4G connection to the internet?

Thanks,

Alan.

yes, the sensors are connected to the 4g router, but these are no lan cables, smal tiny cables to fix via screw driver.
But this is also not relevant, just sensors.

The router is just connected to internet via 4G.
