I Cee emM Pee you!

An open invitation to D-Link, NetGear, etc.  DISABLE ANYTHING IN YOUR DAMNED ROUTERS THAT MIGHT FILTER ICMP UNREACHABLEs.

We’ve been seeing occasional problems with a tunnel “somewhere” on the internet getting into our path.  It shouldn’t be a problem except that it seems a lot of firewalls still filter ICMP Unreachable’s at the least.

DON’T DO THAT.
