I am now at SILCHER location.
when I connect to AR750-Silcher 192.168.17.1 I can reach only admininterface of AR750-Conway 192.168.18.1
I can not reach other adresses 192.168.18.x
There is also only only a connection between the AR750s. No connection to the LANs behind them.
how can we solve this Problem?
I have found a particulary solution:
after setting the guest-network it was possible to set “Configure LAN IP and Access Control” as follows:
now is the local LAN 192.168.9.x visible and accessible in both sites and in OpenVPN Clients 
open is: the LAN on the right side (192.168.18.x) is only accessible local (not in left side, not in Open VPN)
The right sis ist configured as follows:
what is to do, to make the right side 192.168.18.x accessible also from both sides?
I still don’t understand where did you use 192.168.9.x?
1.make sure that the IP Address of the OpenVPN Server is different between 2 devices
2.then setting the left side:
3.then setting the right side:
4.then restart the s2s to try
“I still don’t understand where did you use 192.168.9.x?”
This origin LAN on FritzBox 6490 with more than 122 Devices (Site SILCHER)
in this time the s2s is down .
GL740 ist not in GoodClood
I have done this changes . I understand now the collission of then GL standard Guest 192.168.9.x
with my origin LAN 192.168.9.x.
This was correctet in setting Guestnet to another range.
your problem is the route setting，pls manually let the devices online in GoodCloud and you must set different OpenVPN Server IP address between 2 devices, then add the route on each other.
Leo, perhaps you have solved the origin problem
But now exist then main problem, that s2s down since 48h
please solve the main problem per email via support
my priority problem ist, that the s2s ist down!
please let us solve this problem via Support-Email

he ist connected to GoodCloud
he cannot added to s2s 
I think the reason is Firmware 3025
s2s neeed 3026
update is not available
what is to do?
greetings Thomas
Hallo Leo,
inzwischen ist fast ein Jahr vergangen. Wegen Corona war ich seit März 2020 zuhause und habe meine 3 AR750 kaum benutzt.
Inzwischen wollte ich AR750 “Silcher” wieder dazu verwenden, um per OpenVPN mit dem Smartphone im homeNetz zu sein.
Leider funktioniert das neu erzeugte Config-file nicht auf meine Android-Smartphone.
Wie ich weiterhin sehen konnte hat “AR750 Silcher” nun die Firmware 3.105 , die beiden anderen sind bei 3.027 geblieben und lassen sich nicht updaten.
Ich bitte um Hilfe besonders bei der OpenVPN Problematik.
in meiner Fritzbox sind noch die bisherigen Weiterleitungen enthalten:
ich danke für deine Hilfe

Could you give more detail about how you setup the OpenVPN server?
By the way, those three AR750, they are in a Site to Site network, but they have same public IP address. Site to Site is for those devices in different location(will have different public IP address).
I have GoodCloud Site to Site successfully set up and can access devices on both sites from the other.
Is it possible for all internet data for a travel router to go over GoodCloud site to site?
If so, what settings do I need?
No.
Only some data will go over GoodCloud Site to Site.
I think what you need is to setup a WireGuard Server.
You can read the link below.
@Leo is it possible to add a new node to an existing s2s tunnel? We plan to add a lot of devices so it would be great if we can add new devices without deleting and reconfiguring the s2s tunnel?
Sorry - i found it - in the options item from the list view, so its all ok - from here I can add new nodes.
Each Site to Site network can add up to ten devices.
