That still doesn't work for me:

anilss@anilss:~/Linaro$ ssh -p 8022 root@anilss
ssh: connect to host anilss port 8022: Connection refused

Per ARM, the bridge support is NOT available on foundation model..though their user guide mentions it. I am tried the above using nat.

I don't need to go outside from within the model, but that's probably
of network configuration of the linux distro installed in the model.

However, I am able to ssh to the model:
ssh -p 8022 root@HOSTNAME (where HOSTNAME=name of the machine on which
you start the model)
