I am using DDS Ping to test out communication between two networks but run into problems with the NAT IP address. Here is the setup.
Server A has IP address 172.5.1.100 on network A and the NDDS_DISCOVERY_PEERS is 12@udpv4://172.5.18.200,12@udpv4://172.5.1.100
Server B has internal IP address 10.3.1.5 on network B and external IP address of 172.5.18.200. The NDDS_DISCOVERY_PEERS is 12@udpv4://172.5.18.200,12@udpv4://172.5.1.100
Both servers are running Windows 10 and the network profiles are private and firewalls are off.
