vpnc working under Virtualbox under Windows but not on Linux host
Our company uses a customized vpnc (based on and almost the same as vpnc 0.5.3). I first tested it on a Windows host under Virtualbox everything works straight away. But when I want to use it on a Linux host directly it always ends in "No response from target". I have tested this on Fedora 12 and the latest Ubuntu.
I thought of firewall settings but iptables -L on Ubuntu returns an empty list even.
Anyone has an idea what else it might be? Thank you in advance.
