my network is look like this dsa-3100-->dfl-800-->switch-->servers and client PC

my problem is how do I port forward a server or a client PC which are is inside in my network which I want to access outside. I already port forward the machine in dsa-3100 before and I can access it outside, but when I put the dfl-3100 after my dsa-3100 I cannot access the machine at all. Please Help.

You need make two rules
SAT wan/all-nets core/wan_ip yourservice (SAT: new destination = yourprivatehost)
Allow wan/all-nets core/wan_ip yourservice
Client should accept external connections and have DFL as default gateway. If you can change this policies, change second rule - action from Allow to NAT.

I'm having similar problems but I really don't understand the logic so far...

In my case the network looks like this: Cisco 2611 (ISP) --> DFL-800--> Switch-->Server and Client PCs

I receive the following instruction: "configure the Router (create a NAT) so that all external requests to our public IP address on HTTP (80); HTTPS (443); SMTP (25); and POP (110) ports are redirected to the mail server".

Then I configure this on the DFL-800:

******************************************************************************

Name                         Action                       Source                       Destination                 Service

HTTP_Forward             NAT                           wan1                         Server                       http
HTTPS_Forward           NAT                           wan1                         Server                       https
SMTP_Forward             NAT                           wan1                         Server                      smtp
POP_Forward               NAT                           wan1                         Server                       pop


*****************************************************************************
Now, that configuration was supposed to make our mail server available but we are not currently able to receive any email messages.

What am I doing wrong?

SephirothsHell; if you follow the previous nessage as it is and have no joy that may be due to the fact that Cisco is acting also as nat device and then you may need to create the same rule on the cisco and redirect thise to the wan1 ip of DFL.

Best solution is to configure cisco in bridge mode.

Thanks for the tip.

Thank you dan. I follow this and it works. This is what I did.
address book--> add virtual ip of my server
then follow the configuration stated above.

Weeeeheeee...
