OSX GNS3 and tuntap

Im trying to do some network testing in GNS3 in OSX I have RouterOS in a Virtualbox guest in GNS3 and an XP virtual machine connects to it no issue I can run Winbox in XP and connect to RouterOS but I installed Tuntap which is a virtual network interface driver which is configured by using the Cloud link in GNS3. Im trying to work out how to convert this guide for Cisco routers to RouterOS.

I have completed this guide using a Cisco router and it works has anyone successfully done this with RouterOS and give me some ideas?

Thanks

Issue resolved on “Mavericks” other versions of OSX will differ

In GNS3 you have to connect the cloud to /dev/tap0 in the NIOTAP tab

in OSX at the terminal ..

sudo ifconfig bridge0 create
sudo ifconfig bridge0 addm en0
sudo ifconfig bridge0 addm tap0
sudo ifconfig bridge0 up
ifconfig ;#To check

and to assign an ip via dhcp from a physical router

sudo ipconfig set bridge0 DHCP

Just got to work out how to get Winbox on the host system to connect across the bridge interface to RouterOS as a guest within GNS3 I can successfully ping to the virtual RouterOS machine from OSX using the

ping -S 192.168.1.17 192.168.1.19

but can’t connect with Winbox

Have you managed to solve this?

Thank you
