        Are you sure that at this point 134.95.19.15 (lrv)
is not configured on some interface in lvr8? May be not on
eth2, may be on another interface? Please, do 'ip a' and save
the output at that point, showing only eth2 is absolutely not enough.
Do you know that Linux can reply to requests coming from eth2
even if the local IP is configured on dummy0, for example?
