Thanks for the tips. I'd forgotten about traceroute - I'm not a network guy, obviously. I can confirm for sure now that the IBMi is finding our local server.
Now to figure out why the IBMi software is being blocked from seeing the services on said server. Or find a good network tech.
Thanks
Bob

I'm with Jack on this one.
If you have a detailed network diagram showing the IBMi and the Windows Server and all the bits in between then we would have a starting point.
If you want to check the successful ping to see where it is going do a TRCTCPRTE and look at the hops - you will be able to tell if the traffic is going to your network.
From what you have said I would be guessing the VPN tunnel is only interested in traffic specifically for the IBMi address - Ask the people that set up the tunnel for the ACL's for each end of the tunnel to see what the interested traffic is.
Then seek the help of a good network tech.
Cheers
Don

Subject: Hosted IBMi connecting to local server
Sent by: "MIDRANGE-L" <midrange-l-bounces@xxxxxxxxxxxxxxxxxx>
Hoping someone can help me here. This is more of a networking issue, I
think:
We have purchased a new IBMi based software package that requires connecting to a service installed on Windows Server. Our IBMi is hosted offsite and connected to our network via a VPN tunnel with a 172.20 numbering scheme. The Windows Server is local with a 192.168 scheme.
We can ping the local server IP address from the IBMi, but are unable to connect to the Windows service from within the IBM software. My guess is that when we are performing the ping to the 192.168 address, it's finding a device in the hosting site's data center? The ping result comes back split-second.
The only input I've received from our hosting provider is that we should change the IP address of our Windows Server to match the VPN tunnel scheme. But that brings up a whole host of other issues as that's our primary domain server for the local network.
So, I attempted to change the IP address of a local Win10Pro desktop to be in the 172.20 scheme, but I obviously did something wrong as it lost all network connectivity. Had to change it back.
The hosting provider hasn't responded to any of my follow-up questions and the IBMi software vendor doesn't have the networking expertise to help either.
Anyone have any ideas?
Thanks
