I've got a computer with OpenVPN server behind the NAT. When I try to connect to it from client side and I got following error:
read UDPv4: Connection reset by peer (WSAECONNRESET) (code=10054)
I've configured forwarding for 1194 port in my router for both TCP and UDP. Here is config file for server:
port 1194
proto udp
dev tun
ca /etc/openvpn/easy-rsa/keys/ca.crt
cert /etc/openvpn/easy-rsa/keys/server.crt
key /etc/openvpn/easy-rsa/keys/server.key # This file should be kept secret
dh dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
keepalive 10 120
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 3
And here are my client's configuration:
client
dev tun
proto udp
remote XXX.XXX.XXX.XXX 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert my-laptop.crt
key my-laptop.key
ns-cert-type server
comp-lzo
verb 3
I've tried to follow this Quick Start tutorial but for some reason it didn't help me to start quickly.

Check your certificates - (Use OpenSSL to do this). I've seen this error when trying to use a malformed certificate and/or key.
If your certificates are fine - try switching to TCP and see if that helps.
