Deputy Sheriffs Tom A320 4915 Posted January 21, 2016 Deputy Sheriffs Share Posted January 21, 2016 Why do you configure port forwarding and simultaneously use a vpn tool like Hamachi? You use either one or the other. A working ping is not a final proof for a proper connection, i.e. firewall configuration. Ping utilizes the ICMP protocol, which is a network layer protocol just like IPv4, IPv6 etc, hence it uses no TCP/UDP port numbers. CFD uses UDP as network layer protocol via two ports. So Ping and CFD are two totally different things. A working Ping has therefore no real significance for CFD. I wouldn't be too sure that you and your friend really have all firewalls disabled. Your windows comes with a firewall and in many cases your anti viral / security software as well. Make sure to have those configured properly as well. Have you worked yourself through the current CFD Guides (OVPA)? Link to comment Share on other sites More sharing options...
DaveCT2003 2553 Posted January 21, 2016 Share Posted January 21, 2016 Tom's right on the money regarding the PING and Protocols used. I also agree with him that you guys don't have an open UDP pathway between the two computers - HOWEVER THIS IS VERY EASY TO FIX. Now, I strongly discourage you from using Hamachi, and you can read more about why in the OVPA Guide. Port Forwarding is the better option and is very easy to establish. 1. Be sure that your Router's have ports 6881 and 6882 forwarded for the UDP Protocol. 2. Be sure that your Software Firewalls allow for Incoming and Outgoing UDP communications. You can make this as loose or as restrictive as you wish by going so far as only allowing the communications to certain ports (6881 & 6882) or even certain IP Address (one another Public IP addresses). For complete information, please see the OVPA Guide (currently being revised) which is pinned to the top of the CFD forum. Link to comment Share on other sites More sharing options...
