I don’t have much experience with networks…
This is the answer of /interface print
0 R ether1 ether 1500 1600 9500 D4:CA:6D:E8:58:81
1 ether2 ether 1500 1600 9500 D4:CA:6D:E8:58:82
2 R ether3 ether 1496 1500 9116 D4:CA:6D:E8:58:83
3 R Data vlan 1500 1496 D4:CA:6D:E8:58:83
4 R Guests vlan 1500 1496 D4:CA:6D:E8:58:83

6 R VoIP vlan 1500 1496 D4:CA:6D:E8:58:83
7 R pptp-RN pptp-out 1300

I didn’t make the network. I’m just trying to administrate it.

which one of these lines connects microtik server to the Internet

First of all, thanks for your help!
The line is ether1

I think you have already guess, but I think that the problem is with the tool fetch command. I have tried with different very simples (from the mikrotik fetch wiki) examples and I receive the same error.
Something wrong with my configuration, but don’t know where to start.

Replace this:

# get the current IP address from the internet (in case of double-nat)
/tool fetch mode=http address="checkip.dyndns.org" src-path="/" dst-path="/dyndns.checkip.html"
:local result [/file get dyndns.checkip.html contents]

# parse the current IP result
:local resultLen [:len $result]
:local startLoc [:find $result ": " -1]
:set startLoc ($startLoc + 2)
:local endLoc [:find $result "</body>" -1]
:global currentIP [:pick $result $startLoc $endLoc]

To this:

:global currentIP [:resolve myip.opendns.com server=208.67.222.222];
