I have an openvpn running on a remote server through which multiple clients access internet. Now it's working via firewall and NAT/forwarding by iptables.
When I first set it up without firewall and forwarding/NAT, it didn't work, after connecting to the server, a client would stuck at "looking up the website..."
Is there any way to set it up without NAT and firewall/forwarding, though? What are procs and cons?
