hello every body , i emulated 3 mikrotik routers using GNS (like in the photo) i configured them all ,static route was reachable but the routers cant ping each others ,any idea why ?
P.S all of routers can access the internet
Normally, when I am having this problem its because of how the network adapter is configured. With GNS3 and Virtual Box this can be quite challenging and unfortunately its not always well documented. In all my all-MikroTik GNS3 labs, I create a host adapter for each link. Sometimes, this can be several host adapters. In Virtual Box, you have to play with the network interfaces to get them on the same adapter. Of course, this will create a challenge if there is more than 4 connections. Strangely, enough, if there is a Cisco image between each router, that problem is not present. That is what I do when I have several connections to virtualize.
Usually this can be caused by a network configuration problem. Is your network routed or are you using masquerades?
