routerOS virtualbox virtualization problem

hello,

i am new in routerOS … so first i am trying to virtualize it and learn it.

i created 3 routerOS 3.30 virtual machines in sun vuirtualbox . i connected it with internal network(setting in virtual box).
machines are connected in this way:
mikrotik 1 …mikrotik 2…mikrotik 3

what i did:
i addded IP’s to each interface and to machines 1 and 3 added default route(gateway) to mikrotik 2.

ping from machine 1 to 2(or 2 to 1) is OK, from 2 to 3(or 3 to 2) is OK too,
but from 1 to 3(or 3 to 1) it writes timeout. …so i think it is routing problem, or not?
i dont know if there is something next requiered to configure on routerOS.

any ideas?
thanks

Obviously it’s a problem with either virtualbox or your virtual network setup.

If you have a specific issue with RouterOS, post it here. People on here want to work on RouterOS, not virtualbox.

Note: there are Wiki articles and Manuals that can be read by simply searching:
“Mikrotik Wiki” and “Mikrotik User Manual”
