Hello dear group member,
I wanted to interconnect 2 offices to allow access to certain machines (servers) that are located between each office but also to the presence controller. In each office I have a Mikrotik router with public IP addresses. In one office I use the hotspot for all users.
I used the IPSEC tunnel and the configurations worked fine. When I try to access a machine in another office I can't do it, even when I ping one of the machines it doesn't go through but the ping of the local addresses of each router goes through each office without using public IP and without any problem. Some local IP their ping sends an error message I have just joined this post.
I'm looking for an expert who can help me, even if I have to pay for it.

Host prohibited is an ICMP answer sent by router which means "this traffic is not allowed to go through this router".
I'd check firewall on both routers. Do you have forward rule enabled?
