Manual Outbound NAT Does Not Work
-
Steve,
I removed all manual outbound rules, and than I marked automatic outbound rule generation.
Than I have created a new port forwarding rule.
Rules is atached.
Does it work like that?
-
As I said before the source port from the clients will not be 1251 but some high random number. Change the source port to 'any'.
Otherwise that should work.Steve

Steve,
Source port should not be "any". because my customer wants to get out with a port from lan . but we can give high random port. Which port should we use?
-
You are able to set the source port in the customers application?
Are you sure you've understood the difference between the source and destination ports? Neither of those are the translated nat port.
Look at my test rule. The source port is 'any' because my browser/OS chooses a port at random, I have no way of knowing what it will be.Steve
-
Steve,
That's right.
We're using diffrent software our local network. For this reason, this software will be select . it should not random port. -
Ok, well even if you can set the source port setting the rule to 'any' will still catch the traffic as long as the destination port is correct, 1251 in your example.
Have you tested it?
Steve

mehmetyayia, assuming that what you're trying to achieve is outgoing port 1251 to be translated to outgoing port 25, Steve is correct - set your source port to any, and the destination port to 1251. The source port is 99% of the time an ephemeral port on the client accessing the service (in this case, your specialized machine). You can confirm this on the machine by running 'netstat -an | grep :1251' in *nix or 'netstat -an | find ":1251"' in Windows. If it's in the second IP address column, that is the destination port. If it's in the first, it is indeed the source port. My bet is it's in the destination.

thank you all,
I did your said appropriate. Final rule is atached.
I didn't tried yet. Because I'm away from our office.
I'll give your information.

The source address must be 'LAN net' not 'LAN address'. Sorry I missed that before.

Steve,
There are only lan subnet and lan address in the source adress . I'm using LAN subnet.
is it? -
Yes 'LAN subnet'. It's displayed as 'LAN net' in the rule table. Confusing. ;)
Steve

Steve,
really thank you for everything. I'll try today and than I'll back to you. -
Yes 'LAN subnet'. It's displayed as 'LAN net' in the rule table. Confusing. ;)
There have been enough queries about this inconsistency, I bit the bullet and submitted a pull request to make it all say "LAN net", "WAN net" rather than using "subnet" in some places:

Took only a few minutes to make the changes, we will all save more time than that in answering queries.
