Cosy+ Ethernet - Cannot ping WAN address - VPN tunnel is working

I am having an issue with communicating to a Cosy+ WAN port.  The Cosy+ can see the internet and the VPN tunnel is working but when I attempt to ping or open the browser through the WAN port IP address I get no response. 

My IT department believes it is a firewall issue on the Cosy+ side.  They indicated it could be with the ICMP traffic being allowed.  I have not been able to locate anything with the ICMP settings.

Ultimately, I want to use the NAT 1:1 to communicate plant network to the PLC.

  Hi Ken, 

  This is the default behavior of the Cosy+. You will need to change the WANitProt setting in the comcfg.txt file (Setup > System > Storage > Edit COM cfg). 

  

  Set to 2 to allow all traffic on the WAN. 

  You can find instructions for NAT 1:1 here: kb-0289-00-en-connect-to-devices-on-ewon-lan-from-computer-on-remote-site.pdf
