Data forwarding from Cosy 131 to my server

Hi, Am using an HMI which is recording the data to my server and since i installed the EWON am having issues of pushing the data from EWON to my server,I have changed to the following paramter.
NatItf = 2 (Nat and TF on WAN)
• VPNRedirect = 0 (Allow traffic outside the VPN tunnel)
• FwrdToWAN = 1 (Forward LAN traffic to
Ireceived the data on my server for serval days then it stopped again to download, I don’t know where the issue come from could you please advice ?

Make sure that you have the default gateway set on the HMI to be the LAN address of the Ewon. Also, make sure that you have a good DNS server address in the HMI. You can use a public DNS address like 8.8.8.8.
