but … when I try connect from remote location i get

Sat Jun 28 22:38:05 2014 UDPv4 link local (bound): [undef]
Sat Jun 28 22:38:05 2014 UDPv4 link remote: [AF_INET]79.xxx.xxx.69:1194

pfsense version is: 2.1.4-RELEASE (i386)

got WAN rule
Proto Source Port Destination Port Gateway Queue
IPv4 UDP * * WAN address 1194 (OpenVPN) * none

also got openvpn rule
Proto Source Port Destination Port Gateway Queue
IPv4 UDP * * * 1194 (OpenVPN) * none

I have used openvpn client export package to create vpntest-udp-1194-vpntest-config.ovpn file, used at remote machine.
No matter which remote machine i use (windows, linux) always get undef error.
Also tried turn on OPT1 interface, adding manual NAT … no progress.
