+If you get the following error:  **vpnc-connect: no response from target**\\
+try adding the line below to your configuration file (unibz.conf)
+**NAT Traversal Mode cisco-udp**
+----
+When one attempts to connect to their VPN after installing and configuring vpnc on Ubuntu Oneiric,\\
+the following error occurs:
+<code>
+root@ubuntu:~# vpnc-connect
+Error: either "to" is duplicate, or "ipid" is a garbage.
+</code>
+It appears that the Ubuntu package vpnc comes with an old version of vpnc-script.\\
+This script is what sets up all the addresses and routes for you. The OpenConnect project\\
+provides an updated / revised release of this script. Download the latest copy from [[http://git.infradead.org/users/dwmw2/vpnc-scripts.git/blob_plain/HEAD:/vpnc-script|here]].\\
+Replace the vpnc-script script that comes with the Ubuntu vpnc package: /etc/vpnc/vpnc-script
+----
+Access via ssh not possible, MTU value to high!
+In some cases the MTU value is too high, which results in an very strange
+situation: ping works, but ssh hangs at this point:
+...
+debug1: sending SSH2_MSG_KEX_ECDH_INIT
+debug1: expecting SSH2_MSG_KEX_ECDH_REPLY
+There are 2 bug reports for this:\\
+https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1110787\\
+https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1254085
+and a possible solution/workaround for Linux Mint:
+https://community.hide.me/threads/setup-problem-on-linux-mint-17.1839/
+Check the current MTU value:
+  ip link | grep mtu
+Set MTU value on interface eth0 to 1392
+  /sbin/ifconfig eth0 mtu 1392
+----
+Allow local (LAN) access when using VPN (MacOS)
