I have recently changed my 2003 server st.editon, to have directly acess to
internet
I have a new networkadapter which I connect directly to a xDSL connection
and an other networkadapter for the simple internal network. Active
directory, DNS and DHCP is installed.(all with same IP-adr.192.168.0.1 ). DNS
is set to forward to the ISP- 2 DNS-servers. I also installed ISA-server 2004
on the same machine, but I disabled it. (My main intension was to share
Internet and to obtain a VPN-connection from outside.)
The internal adapter is configured with 192.168.0.1 (inside scope ) without
gateway adress and internal DNS 192.168.0.1 . The ext.adapter conf. with
fixed IP from ISP (84.xxx.xxx.x) with ISP gateway IP and their DNS-servers
Internet functioned in a way the first day except from that the Internet
connection apparently stopped to work after a few minutes both on the server
and on the local clients. After a while it started to respond again. Now it
don't work at all.
If I bridge the adapters I can use Internet on the server, but networking is
then  not possible because the bridge get the the fixed routeradress (84.
...). If I Ping www.microsoft.com result in a totally blank MS-dos field. If
I ping with a external "dotted" IP-adresse I get messsage on timeout .If I
ping internal IP or the ext- adapter the pingresult is OK
In the DNS-property box  i try a test in the MONITOR tab. The DNS respond,
but the recursive test fails. The main problem seems to be the connection
between the internal adapter and the ext. adapter perhaps because the DNS do
not forward requests to ext. DNS. Has anyone any suggestion on what is wrong
