I'm trying to learn if shorewall can drop/reject PPP LCP traffic.
I have a Bering/LEAF setup running shorewall and also pppoe for shared DSL 
connection.  'loc' is eth1, 'net' is ppp0/eth0One of the machines in 'loc' zone 
has an unknown application running that manages to send LCP TERMREQ commands 
that shutdown the pppoe link, which obviously affects all users.Ideally I would 
locate the bad unknown application but am having trouble identifying it.Is 
there a shorewall rule that I can add to prevent the unwanted PPP LCP traffic 
from getting onto 'fw' from 'loc'?
Appreciate any help offered (or redirection if I have the concept wrong), thanks
