I thought I had removed it all from the code that I posted, but I must have missed one. As it says just under that code, the idea is that the IP header will begin at the point in the array that is the size of the ethernet header, and in that case, + the size of the MPLS header I was inserting.

Regards, -- Jeremie In the first code snippet, there is:
