[PLUG] Verizon DSL/incoming conn. problem

[Sandhitsu R Das <sudas@seas.upenn.edu>]

I just set up my linux box with roaring penguin pppoe. It works fine
except for one thing. I don't seem to able to connect to my machine from
the outside world.

When I had DCANet I had a static IP so it was easy. This time I set up
DynDNS and tried to connect - the name resolution seems to be working
fine.

I can't even ping my machine from outside although I can traceroute all
right.

If I ping from a local shell, I get the following error:
sendto: No buffer space available

Same error with nmap.

Any help is appreciated.
-Sandy
