Helmholz REX300 - VPN Connection Tips and Tricks

Quick Start Guide REX 300 19
5.2 Tips and tricks
- If the connection to the myREX24 portal does not work on the rst try, please
install our „shCHECK“ testing tool on a PC. This free program will check whether
the ports needed to successfully establish a connection to the myREX24 portal are
open. This test can be carried out both on the network from which a REX router is
to create a connection to the Internet and from a PC with Internet access on which
the shDIALUP dial-up software has been installed.
- In order to be able to establish a connection to myREX24, at least one of the TCP
ports (80, 1194, or 443) required for the VPN tunnel must be open.
- The required outbound TPC/IP address of the portal server is 5.39.123.5
- Alternatively, you can also view the status of your machines by calling it up directly
from your browser: https://vpn2.myrex24.net. Please use your shDIALUP access
data to log in. After successfully logging in, device congurations can be modied
if necessary and made available on the CTM, and existing WEB2go sessions can be
opened.
- In the event that the provider interrupts the connection of your REX 300 router
during GSM remote maintenance, this may have taken place for the following rea-
sons, among others: incorrect user name/password, ports blocked by the provider
or prepaid SIM cards have no credit left.
- If you would like to use the function for the automatic sending of e-mail of the REX,
the SMTP port 25 may not be blocked.
