I am using DD-WRT with my Buffalo G300NH. I notice in my log files: Wed Oct 10 01:08:25 2012 us=343000 Cannot open /tmp/openvpn/dh.pem for DH parameters: error:02001003:system library:fopen:No such process: error:2006D080:BIO routines:BIO_new_file:no such file I have looked at other answers regarding this error. I have tried to no avail. 755 are chmod rights to /tmp/openvpn. At this point, I can not connect outside my LAN via OpenVPN. My server config looks like this: #mode server #tls-server push "route 192.168.11.1 255.255.255.0" push "dhcp-option DNS 10.8.0.1" server 10.8.0.0 255.255.255.0 port 1194 proto udp dev tun0 ifconfig 10.8.0.1 10.8.0.2 #secret /tmp/static.key ca /tmp/openvpn/ca.crt cert /tmp/openvpn/cert.pem key /tmp/openvpn/key.pem dh /tmp/openvpn/dh.pem keepalive 10 120 comp-lzo persist-key persist-tun verb 5 management localhost 5001 Can someone, knowledgeable, of this error kindly help? i have been going on several days, trying to sort it out. I like all nighters though!!
