4 Network is too bad Contact ISP/Carrier to get better network
4.16 Port forwarding not working
Question: I configure the port forwarding feature correctly, but still no work.
Answer: first, please check the port if block by your ISP/Carrier, because some ISP/Carrier block some
ports for security reason.
For example, the RF-R586m gets WAN IP 27.38.14.223. And the RF-R586’s web port is 80. So from the
other network, try to visit http:// 27.38.14.223:80 if can be okay. If no okay, it means the ISP/Carrier
blocks the 10000 port. Then check with your ISP/Carrier which ports are open for use. Then re-try the
port forwarding feature.
4.17 Serial DTU point-to-point solution not working
Problem: Take two RF-R586. Both support Serial to cellular gateway feature (DTU feature). Configure
one as client, the other as server. But no work.
Answer: First, we confirm that the RF-R586 both are online, and the server’s IP is public IP that can be
ping through from other networks.
Second, we confirm both RF-R586’s DTU feature (Serial to Cellular Feature) are working. We test an
example as follows,
RF-R586 DTU with vodafone SIM as client (in Germany)--- China Telecom as server (In China): working
RF-R586 DTU with vodafone SIM as server (in Germany)--- China Telecom as client (In China): working
RF-R586 DTU with vodafone SIM as client (in Germany)---- RF-R586 DTU with Vodafone SIM as
server (in Germany) : no working
This indicates the two Vodafone SIM cards cannot communicates each other. The Vodafone ISP limit the
two internal’s SIM card’s communication.
You have two ways to solve the problem.
1) Get another SIM card from another ISP to test.
2) Ask the Vodafone ISP to unlimit two Vadafone SIM's communication.
