You can forward to a different port, but you cannot forward to a different protocol. That simply isn’t how TCP/IP works.

Encapsulate your traffic to some tunnel which is supported on ROS and other side.

yeah, use L2TP - it’s UDP-based =)

i cant use L2TP, because of in special time all of such these protocols blocked, so i need to change protocol directly

AFAIR, L2TP is the only UDP-based tunnel in RouterOS

IPsec in NAT-T mode should be using udp/4500.
