protocol 50 (= ESP) unreachable by tedy znamenalo, ze neco na tom
stroji driv ESP umelo a ted neumi.
Nejsem si uplne jisty - ten 88.200.30.145 je ten, na ktery je i ten
druhy, funkcni, tunel ?
Pokud ano, bylo by to opravdu divny - snad jen nejaky lokalni
firewall (ten by ale mel vracet spis administratively prohibited, pokud je
administrator slusnak) nebo hruba chyba konfigurace. Tu tam ale na prvni
pohled nevidim.
Pokud ne a jde o jediny IPSEC na tomto stroji, pak je nejsnazsi
mozna vysvetleni ze doslo ke zmene v instalovanych komponentach ci
pouzivanych knihovnach nebo optionech KERNELu.
