gurvinder I am running OpenVPN server in routed mode with client to client connections enabled in server.conf. I would like to understand, is it really possible to controll client to client connections using IPTABLES on OpenVPN server. I have read several articles which says that you can control client to client connection in routed mode however I would still lite to confirm if it is really doable. Also is it possible to see packets using TCPDUMP when one client is talking to another client in routed configuration with client to client connections enabled in server.conf. I would like someone to share their knowledge regarding the same.
Traffic gurvinder wroteis it really possible to controll client to client connections using IPTABLES on OpenVPN serverYes you can .. Do not use --client-to-client in the server config and then you can control all packets from/to clients with iptables.
gurvinder I have tried that however I wanted to check actual traffic flowing between clients using TCPDUMP, when i tried TCPDUMP it did not show me any packet going through. So my Question is Will i be able to see actual traffic between clients using TCPDUMP when i remove client to client setting from server conf and run in routed mode using option dev tun. Is something specific needs to done in order to see that traffic in TCPDUMP
