I will soon have multiple RouterOS systems behind my linux firewall and need remote access to all routerOS systems. I had no problem mapping port 8291 to one of my systems and having winbox access. How do I do others? For example, if I map port 8292 to a different system, can I start winbox with an address:port?? It seems to ignore the port I request when I put nn.nn.nn.nn:8292 in the address field of winbox. I’m sure this can be done, just don’t know how. Forgive me if I missed something in the docs.
Thanks

Marshall, right now you cannot change Winbox port from default 8291.
Does anyone have suggestions how I can use winbox to access multiple routerOS systems behind my single IP (pppoe) internet connection?? or am I stuck with changing my iptables firewall to map the winbox port to one routerOS system at a time 
Marshall,
your best (and only) option would be to create some kind of VPN tunnel to your linux firewall (or one of the RouterOS machines behind it) and then connect to your RouterOS machines.
Best regards,

the above is what i do and it works great…
