help for vpn mynetname.net

hi everyone … I wanted to know if it is possible to use the mynetname.net vpn service for my following configuration:
i have dynamic public ip connection then i have routerboard 750 and i would like to reach routerboard with vpn. it’s possible? I also tried to put routerboard behind telecom router doing dmz towards routerboard with input in the wan, but the result is always the same. could you help me, maybe with some basic configuration or script that I can then modify?

What vpn protocol do you plan on using ?
Easiest, fastest and most flexible is wireguard, available in ROS7.

Also provide a network diagram so we can understand the relationship of the board to any other routers or ISP modems etc…
What type of ISP connection (fibre, cable, CGNAT, etc..)
Where are you connecting to or from, for your VPN??

in attach my diagram

yhe connection is various: Cable and fibre

as long as you have one Public IP doesn’t matter if it’s dynamic or static, it is possible by using the Mikrotik as a primary router with a WAN interface and the DDNS(IP/Cloud), You could then run whatever VPN server directly at the MT or you could run the VPN at the second router and use DST-NAT* for port forwarding. from main MT router to secondary router.

this is it’s no problem…
“or you could run the VPN at the second router and use DNS-NAT for port forwarding. from main MT router to secondary router.”

can you help me to create a script? and after i modify with my parameters

I’m lacking the scripting skill. but this is a simple firewall rule.
10.10.10.0/24 LAN
10.10.10.1/24 router-A
10.10.10.2/24 router-B
You could easily use IP/Cloud for your VPN connection endpoint.
This example is for L2TP you should change it to whatever protocol/port you want to use as a VPN gateway.

ip/firewall/nat
add action=dst-nat chain=dstnat disabled=yes dst-port=1701,500,4500 in-interface-list=WAN protocol=udp to-addresses=10.10.10.2
add action=dst-nat chain=dstnat disabled=yes in-interface-list=WAN protocol=ipsec-esp to-addresses=10.10.10.2

hi my friends… i have done…thanks…one problem again…when i connect to vpn, how i access at my routerboad from winbox’?
