dear all

when user are going to send request to mail.abcde.com:80 , i want that user's request forward to mail.abcde.com:8080 directly.
in other word when domain is exactly 'mail.abcde.com' (not for other domain) this process to be happened.

i have done this issue in 3 step :

Step 1 : Create Layer7 Protocol :

# NAME REGEXP
0 mail.abcde.com ^.+(mail.abcde.com).*$

STEP 2 : Create a Mangle
chain=prerouting action=mark-connection new-connection-mark=MailServerConnection passthrough=no layer7-protocol=mail.abcde.com protocol=tcp log=no log-prefix=""

STEP 3 : Create NAT
chain=dstnat action=dst-nat to-addresses=192.168.100.100 to-ports=8080 protocol=tcp dst-address=MY_PUBLIC_IP connection-mark=MailServerConnection dst-port=80 log=no log-prefix=""

Mangle are receiving packets when user are going to send request to mail.abcde.com:80 but NAT not working !

any idea?

any idea ????

It doesn't work like this. See e.g. this thread about similar problem.

Thank you for your replay, so we don't have any solution for this in mikrotik OS

This is not a matter of "no solution in RouterOS", what you want to do is simply impossible in networking!
You are trying to redirect a connection setup based on things you find in a running connection.
That requires "crystal ball" functionality.

Unless all you were really looking for was this.

That is old and should probably be removed. Today, an address list can simply be set to a DNS name and it
will do what that script does. But, it is not at all related to the question asked in this topic...
