After all the discussion, the difference of last hop of the trace (from original email)
15 89.1.148.230.dynamic.barak-online.net (89.1.148.230) 251.923 ms 256.817 ms * And the ping result 64 bytes from 89.1.148.230: icmp_seq=6 ttl=240 time=190 ms is still quite interesting. I assumed the last hop is the cisco 871 (IP=89.1.148.230). It will be good to know what cause the difference if you have full controll of the 871.

Lower than 1500 mtu always requires some kind of hack in real life.
That would be the adjust-mss which is the hack-of-choice
note that using 'adjust-mss' only adjusts the MSS for TCP. it won't do much good for already-encapsulated IPSec traffic with protocol 47 or tunneled over UDP...
