OpenVPN – unable to ping LAN

All,

I have an OpenVPN server setup in our Production environment with one client OpenVPN server connected to it. I am setting up a second client connected to the same VPN server. I believe my configuration is correct because I the tunnel came up, and I am able to ping both sides of the tunnel from each of the Client and Server. I have a PC on each side of the tunnel that need the ability to communicate.

NetworkA – 172.21.0.0/16
NetworkB – 192.168.1.0/24

PC-A (172.21.0.101) is behind the OpenVPN Server (172.21.7.13) and can ping the OpenVPN Server and the OpenVPN client. It can successfully ping 192.168.1.29 (OpenVPN client)

PC-B (192.168.1.240) is behind OpenVPN Client, and it can ping the OpenVPN client (192.168.1.29). PC-B cannot ping the OpenVPN Server or PC-A.

Ideally I need these machines to be able to talk, but I seem to be missing something.

Below is the Route Print from PC-A:

I have the firewalls on both remote PC’s turned off at this time. PC-B is an EC2 instance in AWS, but I have allowed ICMP from any location at this time. I am kind of confused to why this would not be working, so any advice is much appreciated.

Please let me know if anymore information is required here.

Thanks
