Software Connection to other Ports Blocked

Post by gsasscer » Mon Apr 18, 2022 7:06 pm

Have Softether set up with Open VPN, firewall rules set to allow connection, both loaded on a virtual server in AWS cloud. Can connect. Can see and transfer files back and forth.

Problem: Running software across this VPN connection. I doesn't look like the VPN is allowing or is not enabled to allow pass-thru connection to other ports on the server... example: The software we are attempting to run communicates through ports 1100, 1700, 2100, 17000, and 27000. The first routine looks at port 27000 and is never making it there.

Firewall rules are also set to allow the software ports. The software runs on the virtual server without an error. We map a drive to the correct folder on the server and nothing... the program ports appear to not be getting data.

What can/should I check?

It looks like AWS VPC with a public IP NIC and Windows OS with SoftEther server and vHUB on SecureNAT+vNAT, correct? If so, you may have to switch to VPC with public and private subnets with port forwarding, NAT and DHCP. Then disable SecureNAT and enable local bridge.
