After all the discussion, the difference of last hop of the trace
(from original email)
> 15 184.108.40.206.dynamic.barak-online.net (220.127.116.11) 251.923 ms
256.817 ms *
And the ping result
> 64 bytes from 18.104.22.168: icmp_seq=6 ttl=240 time=190 ms
is still quite interesting. I assumed the last hop is the cisco 871
It will be good to know what cause the difference if you have full
controll of the 871.
