I'm using 1.8.1. I'll try the latest Wireshark. Thanks!

Wireshark are you using? > I can't choose the "Decode As" option in this case, as it is greyed out. How can I force 
Wireshark to decode the 4 bytes after the PPP header as something else, say MPLS in this case? Use the latest version 
of Wireshark, which appears to support dissecting packets with a PPP protocol value of 0x0281 as MPLS-over-PPP?
