I have two networks separated by two ipchains firewall.  Each firewall has 
two NIC as internal and external interfaces.  I am running a SSH type of 
VPN on top of PPP connection.  In order to browse the host from network 
neighborhood, I have setup two NT domain primary servers (for two networks) 
and each has a different NT domain name.  The internal hosts on each side 
are logging in their NT own domain server.  They are having different range 
of IPs.

master side:
IP:  192.168.0.0/24
NT domain server: 192.168.0.2

slave side:
IP:  192.168.4.0/24
NT domain server: 192.168.4.2

So now when I have the PPP connection, I can not ping internal hosts from 
the other side of network, if I start ipchains rules.  It is all right 
without any rule, though.  Also I can't see any host on the other side in 
network neighborhood either with/without any rules.  SSH port is already 
opened.  I guess I have to open some ports for netbios too? or something else?

Any help is aprreciated.
