Re: [WEB400] DNS Question

[John Ross <jross-ml@xxxxxxxxxxxxxxx>]

Is this your problem? The AS/400 on the outside of your fire wall has a
public IP address. And when it needs to get to the AS/400 behind the fire
wall it points to your fire wall's IP address which sees it on port 80 and
forwards it to your AS/400 behind the fire wall. And when they hit a part
that is behind the fire wall the URL is changing to your fire walls IP
address or name. And the fire wall has two ports one for your lan and one
for the Internet. And how this traffic is handles depends on what
connection it comes in on. Now if it was all on one AS/400 I would say set
up two domain names one for external users and one for internal users. Such
as www.company.com  and www.company.net  but you are starting off on one
AS/400 and letting it transfer traffic when it hits a certain section or
CGI program. I am not sure how you can handle this short of having
something (Java script or CGI) on the web server check what IP address the
client connected on and then format the URL based on that. Or you could do
something I really do not recommend is to have an internal DNS that points
to a different IP address then the external DNS points to for the URL
passed back by the first AS/400.
