So, there is no clear answer to you question, as you did not tell us the system (OS and VPN software) you are talking about.Įven if you add that information, it's hard to answer the question, unless one of the members here has the same 'configuration' and is able to test it. Windows) it might be totally different and dependent on the VPN software in use (we have had several reports about problems with WinPcap and VPN clients ). Mentioned the value for 'ARUBAARM UDP Port numbers' as 5555. Expand 'Protocols' and find 'ARUBAERM' ERM stands for Encapsulated Remote Mirroring 4. Open Wireshark and then go to Edit -> Preferences 3. If you already have installed, update it to the latest. On other systems (Linux 'native' IPSEC stack since kernel 2.6) you will see parts of the traffic in clear and other parts only encrypted (strange thing, but that's due to the internal architecture of the IPSEC stack and the way libpcap hooks into the kernel). Download the latest version of Wireshark.
Step-5: After step 4, you should be able to edit the packet. In the Remote Capture Port field, use the default port of 2002, or if you are using a port other than the default, enter the desired port number used to connect Wireshark to the WAP device. Select Stream to a Remote Host from the drop-down menu. Tick ' Enable Packet Editor (Experimental) ', then click ' OK ' to finish. On the WAP, navigate to Troubleshoot > Packet Capture.
Step-4: Click on ' User Interface ' and scroll down to the bottom. If you capture traffic on that virtual interface, you will see the traffic in clear. Following screenshot shows that editing is not enable in my Wireshark. Since the packets are being reassembled on the NIC, Snort is not. While its true that would solve the 'full' packet capture problem, another problem would remain. UPDATE : A reader asked why we couldnt simply change Snorts default snaplen to a larger value to capture the 2900-byte packets. On some systems there is a virtual ipsec interface (like Linux KLIPS). The packet capture truly was 'full' packet capture. on the OS and the way the IPSEC subsystem is integrated into the kernel.
