RE: tcp/ip port mapping and url path

No NAT on the 400.  You need to make the firewall PAT to the appropriate
IP / Port on the 400.  If the URL's are all the same server / IP
address, this makes it more difficult.

For instance:
App1.domain.com = public IP 1
App2.domain.com = public IP 2
App3.domain.com = public IP 3

Then PAT public IP 1 port 80 to as400 ip port 8080 (or what ever port
you used.)
     PAT public IP 2 port 80 to as400 ip port 8081 (or what ever port
you used.)
     PAT public IP 3 port 80 to as400 ip port 8082 (or what ever port
you used.)

Now if you have www.domain.com/app1 and www.domain.com/app2 and
www.domain.com/app3, you can do virtual servers and run all three on the
same IP/Port on your AS400.

Subject: tcp/ip port mapping and url path

Hi Everyone,
 
I've run into a situation with HTTP where I have 3 different HTTP web
instances running on an AS/400 v5r3, and before they go through our
firewall and hit the outside world, I need to bring them all together on
port 80 (default HTTP.)  To clarify, the url paths for all 3 are
different/unique as well.  
 
The other side of this is, when the requests come into our network on
port 80, I need to segregate the requests to their correct ports, before
the requests hit the web server on the 400. I have been looking at a
variety of ways to do this, including NAT on the 400, which seems to be
able to handle all of what I need EXCEPT the segregating by url path.  I
am curious if there are Exit Point Programs available, that may do this
last piece for me.
 
The other question is, if I turn NAT on, will it only affect what I
specify, or will it affect all TCP/IP activity on that machine?
 
I'd really appreciate any advice, comments, etc. you can share with me
on this.
