Hi,
Finally i took some time to read some docs, but i still have some doubts:
PS: I know, quoting may not be beaty - I gotta get a better MUA :-)

Well, I need my host to do forwarding because i want PC_A one net_0 to have
access to PC_B on net_1 and the only conect point is my dual homed host. In
order to do it, it' simply enough to compile ip_forwarding in the kernel
and then echo "1" > /proc/sys/net/ipv4/ip_forward. The option
"optimize
as router not host" is just to disable the copy and checksum technique a
normal host perform, as most of the time i won't be forwarding i'm not
using this option. You may have thought about port_forwarding, haven't you?

I guess those are not OK. As far as i could understand in the BROWSING.txt
we'd
only have one wins server. I think i have a similar problem to browsing across
subnets. I do have 2 subnets but the biggest trouble is that
i have a common host to 2 interfaces. I tryed to start a WINS+LMB+DMB to
net_0
and then LMB to net_1 pointing to the 1o. WINS (172.16.0.2). I used "config
file"
option but i couldn't start 2 nmbd on the same host. Im afraid that with the
first configuration, nmbd is fighting itself when it tryes to elect a DMB
(Domain
Master Browser), what you think? Well, i'm gonna increase logging to see
what's
happening, meanwhile, if someone just know by heart or have a guess what's
may be
going on, could you give a try, too?

May help, especially if we setup 2 Domains ( i guess , i guess ), but there
should
be a way to use just one group.

OK, but ... what you think about DMB elections on 2 different interfaces for
the same Domain ) Sincerely, i didn't understand enough this stuff either!
