Must add some more info:

My kernel config:

cpu             I486_CPU
cpu             I586_CPU
cpu             I686_CPU
ident           DIVERT

makeoptions     DEBUG=-g                # Build kernel with gdb(1) debug 
options IPDIVERT

(the rest like in GENERIC).

Strange thing:

I cannot ping neither the outside interface address nor the inside
