Well, I ran into the same problem, the easiest way I found to fix this was
to get two IPs from your ISP, give one to your PC and the other to your TS,
then connect your TS Ethernet and your PC to a switch and plug in your
modem's LAN side in the same switch, that should solve the problem, at least
it did for me.....
Thanks

What do you have in your stack of equipment?
The way I accomplished it was I configured my 2509 to get its address from
my ISP (cable modem), then connected it to a 2501 with a WAN crossover
cable. I then configured NAT on my 2509 with the Eth being the NAT outside
interface and the WAN being the NAT inside. Then connect your PC to the Eth
of the 2501.
It slightly limits the flexibility of lab set-ups you can create, but I did
not find it too limiting, especially since you can change the address on the
WAN, etc. If you want to get really fancy you can make the 2501 a DHCP
server and hand out addresses to your PC...
Good luck - Rob.

Subject: OT - accessing home lab via the internet
Guys,
Need some help from those of you that have setup Internet access to your
home
labs (for telnetting in while you're at work, etc). Please keep in mind that
I
am trying to do this with only the equipment described below. In other
words,
it would be easy to do what I am trying to do if I had a router with 2
ethernet interfaces, but I don't.
Scenario:
I have a stack of equip that I access via a 2509 whose 8 async cables are
connected to the console of each device. I have cable modem access and have
been successful at getting the e0 on the 2509 to get an IP via DHCP (my
provider offers only dhcp; no static ip). This is accomplished with the
command "ip address dhcp" available on IOS 12.1(2)T.
The pc that I use at home is addressed as 10.0.0.3/24 and I setup a
secondary
ip address on the 2509's e0 as 10.0.0.1/24. Now the tough part. I need to
configure NAT so that I can access the internet via the 2509. I also need
the
2509's e0 to keep getting it's primary ip via dhcp so that I can telnet in
from work. I can get everything to work except that I can't get access to
the
Internet now from my pc. "debug ip nat" output seems to indicate that the
router is not doing NAT for the 10.0.0.3/24, but it is doing NAT for
10.0.0.1/24.
Questions:
1. Can you use NAT to create translations between 2 ip addresses that are
configured on the same interface?
2. Is there an easier way to do this with existing equipment and/or PC
software that I am overlooking?
Thanks,
Bob
