NAT/PAT question

Hi all.

Strange one: I am backhoming traffic from all of my customer's locations to a central location. When traffic going out to the public internet on port 80 arrives at that central location, I would like it to be redirected to another server on port 8080 before it goes out.

ex:

traffic from any:any to www.yahoo.com:80 should be redirected to 192.168.1.2:8080

This _must_ be transparent for the client machines. I'm using a c1720 v.12.2 IPSec

any suggestions on how to do this are very welcome :)

thanks

Re: NAT/PAT question

Hi Matt,

this is going to be relatively quick & easy to implement. Here is what to do ...

1. Setup a proxy server to accept http connections only on port 8080 (from your

client pcs')

2. Change clients internet explorer proxy settings to point to this server &

specifying port 8080 (click on tools, internet options, connection, lan

settings - if using M/S I.E.)

3. On the 1720 rtr issue standard nat cmds with an access list allowing only

the proxy server's ip add to go out the net.

We have the same setup except we use a F/W. Let me know how this goes ...
