[HamWAN PSDR] Scripting help needed

[Rob Martin]

Hello,

I would appreciate some assistance in writing a script to run in a Mikrotik router.

I am trying to get a remote Mikrotik router to phone home by establishing an ovpn tunnel. I am able to deliver my local IP address to the remote router, and store it in its firewall address list. My local IP changes occasionally.

The ovpn tunnel setup does not seem to have a way to directly use a variable for the connect-to address. I need help with a script to perform this.

Here are details of the project:

1.  Add an entry to the list to simulate a separate process that adds entries automatically. I have the this part working already.

/ip firewall address-list
add
  list=K7QJ
  address=97.11.22.33

2.  Add the following ovpn tunnel to simulate an earlier entry in the router setting up the tunnel. This is a slightly edited version of a working tunnel.

/interface ovpn-client
add 
  add-default-route=yes 
  certificate=cert_export_client_QJ.crt_0 
  cipher=aes256 
  comment="Tunnel to K7QJ TS " 
  connect-to=12.34.56.78           **** placeholder IP
  disabled=yes 
  mac-address=00:11:22:33:44:55 
  name=Tnl_K7QJ 
  password=abcdefg
  user=K7QJ_A

3.  Here is where I need help.....   Create a script that will scan the address list, locate the entry K7QJ, and put the address value (97.11.22.33) in a variable.

4.  Add lines to the script that will edit the above tunnel setup as follows:

  connect-to=97.11.22.33       **** where the IP is recovered from the variable
  disabled=no                            **** and the tunnel goes live.

Thanks for any help you might be able to offer.
