from the outside looking in

[Guest]

hey all,
there are some times on our asp.net apps when people on the outside of the
network can't see the app and those of us inside the network can see the app
just fine.

what would be the best way to troubleshoot this? is there a way from the
inside of the network simulate what people will see on the outside? or what
is the normal way of handling this?

thanks,
rodchar

This is more a question of network infrastructure than C#. Something is
misconfigured in your network. It could be one of your routers or firewalls,
or maybe even one of the network adapters in your web server.
How would you simulate what people see on the outside? One way to do it
is to take a PC, disconnect it from the local network, and use a modem to
connect it to an ISP. Another way is dependent on your network topology and
equipment. You may be able to manipulate the routing tables and/or the
default gateway in a PC in such a way that it goes "out" through one router
and then "in" through the one that exposes your server to the Internet, so
you would be seeing what others see from the outside. This is not a task for
the software developers, but for the network engineers.
