@Sebus, calm down man, andriys
,macsrwe and jarda
have explained very well purpose of Quick Set. As an adition would like to point out hardware schema for your RB:
https://i.mt.lv/routerboard/files/Block ... S-2HnD.pdf
I do not want to continue that discution about Quick Set but i suggest to forget about Quick Set and move on; in order to do more complex setups ( like you want and in the future i am pretty sure that would be similar situations) you have to learn to use a lot of options from left menu.
Now, back to your situation. In order to make ether9 main port for internet connection from your ISP ( WAN port as you preffer ) you have to do the following ( i am not a fan of WebFig i am used to use Winbox):
a. since ether9 comes by default in second chip and it has been assigned ether6 as a master port,
you have to remove it from ether6 master port and make it as a standalone port
b. now you have ether9 as a standalone port for your WAN purpose. Now you have to assign it ip address from your ISP.
1. After you logged in via WebFig, from the left menu click on option INTERFACES;
2. then click on ether9 port description ( ether9 );
3. new window will appear from where you have to:
a. if you want to rename interface ether9 to something else like WAN you should do it into name field;
b. on master-port option select drom drop-down menu NONE.
4. hit the "OK" button.
For the sake of example i will presume that you have a public static ip as follows
public ip from ISP: 18.104.22.168/32,
gateway: 22.214.171.124 (will be added automatically for you into routing table -> IP Routes )
From the left menu click on IP option then on ADDRESSES
A. If you have already configured your ISP ip to ether1
a. from the right side, click on ether1 name;
b. from window open select from interface drop-down list ETHER9 instead of ether1;
c. click on "OK" button.
B. If you have not configured already your ISP public address
c. modify NAT rule from you firewall in order to reflect new changes
a. from the right side, click on "Add New" button;
b. into the new window fill in address as follows ( from our example ):
1. Address: 126.96.36.199/32
2. Network: 188.8.131.52
3. Interface: select ether9 from drop-down list
4. hit "ok" button
1. from left menu select IP option then FIREWALL;
2. in the right sie, click on NAT tab from above;
3. i am pretty sure that nat rule it has been already there but defined as out interface for ether1;
4. click on first rule ( where below ACTION head table is writen down MASQUERADE );
5. new window appear, on interface option select ETHER9 from drop-down list;
6. hit "OK" button.
There are other rules into FILTER tab that need to be modified from switching ether1 to ether9. You have to modify them by yourself.
Now you are done; you have managed to configure ether9 as your WAN port, assigned it public ip from your ISP and
assured that nating is defined/working on your new "WAN" interface.
I am pretty sure that you may have other questions too but as an advice, if i may, on future please post here your router configuration too in order for us to make a better understanding of your config and what you want to achieve resulting in a better or quick way to help you.
You can do that my copy&paste code after issuing /export hide-sensitive
command into terminal window, la image below:
Hope it helps.
