GRE advisory

[Alex Bligh <amb () gxn net>]

For those of you who mailed me privately to ask for the URL of the
GRE (and other tunnel) advisory detailing how to detect and prevent
abuse of exchange points etc. to steal third party transit, sorry,
I lost most of your email addresses, but it's at:

http://www.linx.net/tunnel-advisory.txt

(for those who saw it before, no it hasn't changed).
