Po prostu 213.209.165.202 generuje inne czasy z ICMP echo reply a inne
z ICMP time exceeded, a dla ttl=14, owszem - przychodzi odpowiedz z
adresu 213.209.165.202 ale:

12:28:10.818029 213.209.165.202 > XXX.XXX.XXX.XXX: icmp: time exceeded in-transit [tos 0xc0] (ttl 241, id 24918, len 56)

Co dziwne - ping z ttl=14 generuje wlasnie time exceeded, 15-17 nic, a dopiero 18 echo replay.

Zapewne to jest jakiś DNAT czy co...
