I already sent this mail to LARTC mailing list w/ no luck so I hope to find
more hints in this list...
I use '-t mangle ... -j MARK' to mark packets that a rule 'ip rule
fvwmark' will route to a specific table. This is primarily to test if a
connection is available without messing with everybody's routing
table. (Actually I have and 'adsl' teble and an 'isdn' table)
What happens is that packets go to a test host in the internet, come back,
are visible to tcpdump... but not to ping!
I *think* it's a routing problem since ig I use the 'isdn' table as default
ping works normally.
I can't immagine what happens to the packet between being seen by tcpdump
and arriving at ping...
I described my setup a litte more deeply here:
