I have a local network with a CLASS C and a remote network with a
subnet of another CLASS C. Here's the hookup:
'local' end - CLASS C: xxx.xxx.xxx.abc
Netmask: 255.255.255.0
+------+
--------| ADSL |-----------------
| +------+ |
+-------+ ADSL 'modem' |
| HUB | connects to 'dry' |
+-------+ copper to remote |
Local Ethernet Hub site. /
connects to several /
machines and router to remote site
to internet provider. \
\
|
|
'remote' end. SUBNET CLASS C: yyy.yyy.yyy.abc |
Netmask: 255.255.255.240 |
|
+------+ |
| PC | |
+-----+ | NT | +------+ |
| HUB |----| 40 |----| ADSL |-
+-----+ +------+ +------+
Remote Ethernet Hub Remote PC ADSL 'modem'.
connects to several running NT 4.0
machines on remote Server. Ethernet
net. card to remote
net is .17 of
remote subnet of second CLASS C.
Ethernet card to ADSL modem
is .70 of local CLASS C.
We run a local LAN that has several machines (PC's, MAC, Alpha)
and a router connection via T1 to our 'net supplier. Also
connected to the LAN is an ADSL 'modem' that feeds a 'dry' copper
circuit to a remote site.
The copper circuit terminates at the remote site on the matching
ADSL modem and conects to an ethernet card in a PC running NT 4.0
server. A second ethernet card in this same PC connects to the
remote LAN made up of several MACs and PCs.
All machines on the remote LAN can talk to each other and to the
NT server. The NT server can talk to all machines on the local LAN
and access the internet via the router (gateway: .1 of the CLASS C)
The card on the local side of the NT is xxx.xxx.xxx.70 and is part
of the local CLASS C. The card on the remote side of the NT is
yyy.yyy.yyy.17 and is part of a subnet of a _different_ CLASS C.
I have the quintesential firewall.
However, I want users of the machines on the remote LAN to be able
to access the Internet across the ADSL link and subsequently out
the router at .1
I have the remote card in the NT set up with gateway =
yyy.yyy.yyy.70 and I have IP forwarding turned on for both cards.
I have the local card in the NT set up with gateway = yyy.yyy.yyy.1
and I have tried adding a second gateway of xxx.xxx.xxx.17 (the
other card!) but there is no difference either way.
Is it even possible to bridge/route across these two cards with NT
4.0 server or do I need some other software? Is there something I
need to do in DNS tables? Any help would be appreciated.
