Hello,
According to this message: http://sourceforge.net/mailarchive/message.php?msg_id=10639223 OpenVPN adds a cleartext uint16_t length word before every packet, now my question is this: is it always the same word? where is it defined/calculated etc? I tried figuring it out by looking at logs of tcpdump but I was unluky, also taking a look at the source code turned up some results but not quite what I was looking for... I want/need to know this to be able to use l7-filter (an extension to iptables to be able to filter on the data of a package)... Thanks, Bram
