   1 This scenario enables IPComp compression between roadwarrior <b>carol</b> and
   2 gateway <b>moon</b>. Two pings from <b>carol</b> to <b>alice</b> check
   3 the established tunnel with compression. The packet sizes of the two pings
   4 are different because the kernel does not compress small packets.
