Simple Networking/IP Question

Hi Everyone,

I am looking to install Remote Desktop over SSH. I've had a few
connection issues with VNC over SSH and want to try Remote Desktop.

However, to successfully test the operation, I will need to run the
client on a machine and provide it my external IP.

I've heard of issues trying to go outside and back in on your own
network. Is there any truth to this? Are there issues with me using
my external IP from inside my own network?

If so, how the heck does one test this?

Thanks!

Yes there are problems. It creates a situation where the NAT process creates
a packet where both the source and destination MAC address in the packet is
the same address which causes it to fail.

You need more than one public external IP#. you then assing it to a test
machine and do you testing from that machine which is now on the "outside".
If you have a dialup account you can use, then you could do it by dialing up
that account and using it as you base to test from.

Concerning the MAC addres thing here is an article to decribe the situation.
the main context is ISA Server 2000, but the relevant part of the article is
at about the mid point under the subheading of "14120 Errors"
