Very Computer

I have a real strange situation I do not have any idea how to solve:

This is my situation:

                                                   192.168.0.1
                                                   ISDN-NAT-Router
(asuscom 850)

/etc/nsswitch.con   hosts:    files dns
/etc/resolv.conf
     domain eidberg.ch
      nameserver 192.168.0.10

The local DNS-Server is:
options {
        directory    "/var/named";
        forward only;
        forwarders { 146.228.10.16; 146.228.10.15 } ;

Quote:};

I can do all network connections to the internet on all systems exept
the Solaris 8 box.
This solaris 8 box only works with ping, not with http, ftp, telnet,
rlogin.
It is not a hardwareproblem onto my solaris 8 box, because I can do all
the networking
stuff within the internal network. And I have this behaviour onto two
machines (what in fact
is the reason for the Solaris 7 box) but now I rely onto Solaris 8
because of the SunBlade 100.

Every  help is very welcome

Many thanks
