VPN connecting but data only moving in one direction

tgarneau

I set up a vpn using openvpn a week ago and it was working as I needed it to until sometime yesterday(Shared drive and printer access). As far as I know, nothing was changed, although other people do have access to this server.

The server is running Windows Server 2003 and the clients are running Windows XP. I followed the setup guide here: https://community.openvpn.net/openvpn/wiki/Easy_Windows_Guide

The configs from the same config folder with the only changes being for the certs and server address. I'm using a freeDNS address to access the server Since we don't have a static IP. The VPN is connecting and I haven't seen any errors or warnings in the logs. When I ping the server from one of the clients I don't get a response but I can see on the server that the packets received count of the tap adapter increases with each ping but the packets sent count remains at 0. The firewall on the server is currently disabled.

It would seem to me that the problem is server side, correct? Can someone tell me why the server is not responding? What should I look at next?

I've resolved this problem. Somehow, Incoming Connections was enabled ( http://technet.microsoft.com/en-us/library/cc782348(v=ws.10).aspx ). Deleting it from network connections fixed my problem.
