Subject: connect busybox to Endian Firewall OpenVPN
Hey there,
I am trying to connect busybox to an Endian Firewall OpenVPN server without success. OpenVPN server seems to be properly configured for I can get a connection using windows and ubuntu linux. Using busybox, I am reciving some problems, my openvpn.log file output is as follows,
Tue Oct 1 10:13:46 2013 us=899312 UDPv4 READ [0] from [undef]: DATA UNDEF len=-1

I have configured iptables, as you can see below,
iptables -I INPUT 1 -p tcp --dport 1194 -j ACCEPT
iptables -I INPUT 1 -p udp --dport 1194 -j ACCEPT
iptables -I FORWARD 1 --source 192.168.101.0/24 -j ACCEPT
iptables -I FORWARD -i br0 -o tun0 -j ACCEPT
iptables -I FORWARD -i tun0 -o br0 -j ACCEPT
My client configuration file is the following,
#OpenVPN Configuration
cd /opt/dnt/OpenVPN
dev tun
client
cipher BF-CBC
remote 192.168.1.3
rport 1194
proto udp

log /tmp/openvpn.log

Could someone please give me an idea to solve this issue? Any help would be really appreciated.
Kind regards.
