Can RBs do tunneling to accept public IPs like cisco and how

RouterOS Wireless Networking
1

My ISP demands that i put a cisco router before they can give me a public ip but if my router board can do tunneling then they will accept it and pass the public ip address on

i want to find out if its possible and how do i do that configuration. their main issue is security. so no one can pass their security

i quess i have to prove what Mikrotik RB are capable of doing

RouterOS supports the same tunneling as cisco. What kind exactly do they want? IPSec?

i am going to ask them to put it into writting exacty what they want and get back to you

that’s a good plan

All they said is their network is open so we should find a way to get the public ips.
so lets start with how we can use the ipsec to get the public ips
