I have a PLC that pings over NAT 1:1 on WAN, the kepware server can ping it, however kepware itself gives a device not responding error.
Verified that the WAN NAT IP is the PLC (even unplugged ethernet from PLC and saw that the NAT IP quit pinging.)
Hello @Jonathan_L ,
Nat 1:1 is mapping all ports at that second IP address to the IP of the mapped device on the LAN. What kind of connection is Kepware making?
