Zacykleny traceroute - chyba v routovani?

[Boruvka :)]

Zdravim,
    mam server RH 7.1 - 2x eth - jedna sitovka vede do internetu, druha do vnitrni site. Na vnitrni siti jsou mezinarodni IP. Nepouzite IP mam zakazane pomoci ipchains. Pokud pustim zvenku tracroute na povolenou IP, vse je OK, ale pokud pustim traceroute na IP, ktera je zakazana pomoci ipchains, tracerout se stale dokola pokousi IP najit:
Napr. tracroute na IP 194.36.36.30  (IP je zakazana pomoci ipchains) vypise toto:
....
10    194.36.26.13    server.domena.cz
11    194.36.26.13    server.domena.cz
12    194.36.26.13    server.domena.cz
13    194.36.26.13    server.domena.cz
14    194.36.26.13    server.domena.cz
15    194.36.26.13    server.domena.cz
... a takhle porad dokola :(

    Je to normalni nebo mam nekde chybku? Diky za radu Boruvka :)
