PointCloud in RVIZ working with VLP-16 but webinterface doesn't work

edit

I connected with the VLP-16 LiDAR using the following tutorial:

http://wiki.ros.org/velodyne/Tutorial...

using ifconfig i found out that the first ethernet interface was enp24s0 instead of eth0

In wireshark i found out that the ip addres of the LiDAR was 192.168.1.201 so i used:

sudo route add 192.168.42.201 enp24s0

instead of using the standard:

sudo route add 192.168.1.201 enp24s0

i can see the point cloud in RVIZ, but i cannot load the web interface if i type 192.168.42.201 or 192.168.1.201 in my browser.
