Thanks for your answer.

Ok. Solaris by default routed between interfaces of it own. You right:

# ndd -get /dev/ip ip_strict_dst_multihoming   
0

But is it really "the default for most other systems" to forward between 
interfaces with different netwokrs??

Yes and no, I try to make the Solaris box to be a router/forwarder. It had 
worked but no more.  but it is another story :) Now i try to understand how 
solaris networking is done and i found that funny routing "problem".
An example: FreeBSD's  forwarding between interfaces is off by default . I 
think it is in Windows too.

Thank you very much. You help me to understand that i know nothing about 
Solaris networking :)

If my attempt to make a "real router" from that box will fail i will make 
another thread and may be you will help me :)

Tnx and sorry for my terrible English.
