There is no such thing as a serial to Ethernet adapter. It's either 2 IP
addresses to e0, no internet access, another router, or setting up a win2k
box with dual NICs and enabling IP Forwarding (routing). The only
stipulation is that the one particular Win2k box will be plugged into the
production lan ETHERNET segment.
If finding funding for another router such as a 1005 with a serial and
ethernet interface is nigh on impossible, it may be time to reconsider where
you are working.. especially if it is required to support confidence in the
health state of the production network. A 1005 shouldn't cost more than
$300USD.. how expensive is an hour of downtime on the production network
worth? 4 hours? 8 hours? It's simple business politics and accounting..
time to learn how to justify testing gear cost.

ok heres another spanner in the works so to speak, how about if I setup one
of my win2k boxes as a router (in the test Lan) and via a couple of serial
to ethernet adapters (with a 10baseT crossover cable in between) connected
it to the serial connection of the cisco router? surely if feesible that
would make more sense than binding two ips to one ethernet card, (basically
i dont want any packets taking a "short cut" from the test lan to the
production lan) i know this scenario is far fetched but trying to get
funding for such a "minor" project such as wan traffic is nigh on
impossible!! some people have no idea!!
cheers

it is possible, but not advisable in an undetermined lab environment. A
chattering win2k box could cause problems for your production network.
Given limited resources though, I suppose you could do it.
conf t
int e 0
ip address 192.168.1.0 255.255.255.0 (Production Network)
ip address 192.168.100.0 255.255.255.0 secondary (Win2K Lab)
would be sufficient. This would also allow ip routing between the Win2k
lab, and the production network. Running 2 LANs off of 1 segment
though,
you are making all of your production network machines look at the MAC
address broadcasts from your lab. If both are of a substantial size, it
may
create a performance issue on your production network. It is really a
design issue.

thanks for the reply, I wonder is would be possible to run a second ip
off
the ethernet port on my exsisting router (i.e a hub with the connection
to
the company lan and the win2k test lab going into the one ethernet port)
what do you think?
thanks

You can not "add" any interfaces to an existing 2500-series router..
and
like Jenny said, this sounds more like a 2503. Another possibility,
would
be to find another 2501/2503 router, use a back-to-back serial, and use
the
ethernet on that router to your lab. Your lab would look a little like
this:
Outside world
|
(BRI)
|
Cisco 250x ---------(e0)--------LAN
|
(S0)
|
Cisco 250x ---------(e0)--------Win2k Lab

Hi,
I am setting up a test lab environment for a windows 2000 migration and
want
to have access to the outside world, the problem is we have a 2501
router
which currently has the bri and ethernet interfaces in use, I need
another
ethernet interface for the test LAN, is there anyway I could utilise the
serial connections for the test LAN? I m guessing that you cant put
another
ethernet card into the router due to the chassy type...i might be
wrong...help!
cheers in advance
Dan
