Using Windows XP as my internet gateway
I have many question regarding many things in Unix.
here is another.
I have a
Novell 5 server
Windows 2000 advanced server running active directory
Windows 2000 professional server running exchange 2000
Windows XP professional providing my internet gateway through 56K dial up modem (sad I know but my ADSL is awaiting to be installed)
Suse Linux 7.1
all those machines are running thru a 3Com superstack II switch 10/100
all my Windows machines are able to acces the internet via my XP box. is their a way of connecting my Linux machine to also use this XP box as my internet gateway.
I have dynamically assigned IP addresses from my ISP, but with static DNS server addresses.
2000 adv svr = 192.168.0.20 255.255.255.0
2000 pro svr = 192.168.0.30 255.255.255.0
XP pro = 192.168.0.1 255.255.255.0
HP jetdirect EX plus 3 = 192.168.0.10 255.255.255.0
Linux 7.1 = 192.168.0.3 255.255.255.0
Novell 5 192.168.0.2 255.255.255.0
I'm able to ping all the relevent machine on my lan but am unable to ping DNS server at my ISP location.
Can this be done, if so help me.
Also I would like to be able to print to my HP Laserjet 6p thru my JetDirect box, which I can also ping from Linux.
Would it be better if I setup my Novell 5 server as my internet gateway, this will be fine however when I have my ADSL conection installed I won't be able to route this thru novell as it does not have a USB port ( sad also but novell does not need much power, so I'm running it on an old AT machine with a Intel P200 MMX )

Hi,
Until now, we used PPP via an ISDN modem to connect our server to

LEARN ABOUT FREEBSD
nos-tun
NOS-TUN(8) BSD System Manager's Manual NOS-TUN(8)
NAME
nos-tun -- implement ``nos'' or ``ka9q'' style IP over IP tunnel
SYNOPSIS
nos-tun -t tunnel -s source -d destination -p protocol_number [source] target
DESCRIPTION
The nos-tun utility is used to establish an nos style tunnel, (also known as ka9q or IP-IP tunnel) using a tun(4) kernel interface.
Tunnel is the name of the tunnel device /dev/tun0 for example.
Source and destination are the addresses used on the tunnel device. If you configure the tunnel against a cisco router, use a netmask of
``255.255.255.252'' on the cisco. This is because the tunnel is a point-to-point interface in the FreeBSD end, a concept cisco does not
really implement.
Protocol number sets tunnel mode. Original KA9Q NOS uses 94 but many people use 4 on the worldwide backbone of ampr.org.
Target is the address of the remote tunnel device, this must match the source address set on the remote end.
EXAMPLES
This end, a FreeBSD box on address 192.168.59.34:
nos-tun -t /dev/tun0 -s 192.168.61.1 -d 192.168.61.2 192.168.56.45
Remote cisco on address 192.168.56.45:
interface tunnel 0
ip address 192.168.61.2 255.255.255.252
tunnel mode nos
tunnel destination 192.168.59.34
tunnel source 192.168.56.45

Nickolay N. Dudorov <nnd@itfs.nsk.su> wrote the program, Poul-Henning Kamp <phk@FreeBSD.org> wrote the man-page. Isao SEKI
<iseki@gongon.com> added a new flag, IP protocol number.
BUGS
We do not allow for setting our source address for multihomed machines.
