It sounds like what you need is a Cisco consultant to come in and configure
the router for you...Cisco programming can be a challenge
But in answer to your general configuration questions
All ports for Email, RWW, OWA , Sharepoint, etc need to be forwarded to the
SBS to the External NIC address 10.10.X.X (the one connected to the cisco
device)
Your nics are configured just as they should be. All workstations (unless
not part of the domain) should have 192.168 addresses, not 10.10 addresses

Please help as I am tearing my hair out trying to get this working and
have
little experience with Router setups and it seems not to work as I would
expect.
I can get internet access to all workstations but not email or other
services working.
I have installed an SBS2003 server with 2 NIC's and have been running it
okay for a6 months with just a ADSL modem in front of it. However,
recently
the service became more criticle and I have had a few instances of
attempted
hacks. So I am trying to install a CISCO 876 router to control the
internet
access.
Here is the network to be defined :-
Fixed IP provided by ISP - Router external interface as FIXED IP
Router VLAN1 defined as 10.10.10.1, with DHCP
External NIC of SBS2003 10.10.10.2
Internal NIC of SBS2003 192.168.1.101
Workstations have 192.168.1.x addresses, or 10.10.10.x addresses.
Here is what I want to achieve :-
Most user devices will sit off the 192.168.1.x network range. The
10.10.10.1
range will be used for network cameras etc. The SBS2003 server is an
EXCHANGE
email server, DNS server and provides DHCP for workstations on the
192.168.1.x network.
The address 192.168.1.101 needs to recieve all SMTP mail (port 25)
Also I want 443, 444, and VPN ports routed to SBS2003 server.
Address 192.168.1.23 is a Blackberry server and so has to receive messages
for port 3101 both TCP and UDP.
All 192.168.1.x and 10.10.10.x addresses should be able to reach internet.
Please let me know what I need to define in the router (fixed and dynamic
routes), should I use RIP and where NAT should be translating to in the
router to send the smtp email messages and other things to SBS2003 server.
(Should it be the external 10.10.10.2 address or the server address
192.168.1.101 ? )
(I have set it up for both but never get any messages into the mail server
when testing it :-)
I have now dropped it back to the ADSL modem only connection and so cannot
do any specific up to the minute tests)
IPCONFIG /all on both 192.168.1.101 and 10.10.10.2 looked correct
Local internal SBS2003 interface
IP address ----- 192.168.1.101
Subnet mask -- 255.255.255.0
Default gateway
DNS 192.168.1.101
DHCP 192.168.1.101
External SBS2003 interface
IP address ----- 10.10.10.2
Subnet mask -- 255.255.255.0
Default gateway 10.10.10.1
DNS 192.168.1.101
DHCP 192.168.1.101
Thanks in advance
