Re: OpenVPN Client to OpenVPN Server NAT

I have confirmed that the OpenVPN Server sees the connection with TCPdump, but my client on Site A doesn't respond... So it appears I'm correct on my thinking that the client doesn't know to go back through the VPN to reply to the connection! I assume I need some kinda firewall rule to return the tr...

Re: firewalld Multiple WAN IPs 1 interface help

Good to know! That does help a little :) But I am not sure then how to use firewalld to open ports based on source IP. I tried creating zones by source IP address, but this didn't work :(. So, if anyone knows how to open firewall based off WAN IP instead of interface, this would be really helpful!
