Support for public key & alternate ports

I barely use password these days to access my SSH servers. I much
prefer RSA keys so I don't have to memorize long passwords.
Does sshuttle support RSA keys rather than passwords? Can alternate
ports be specified as well ?
It would be nice if it could simply use the servers defined in ssh
config file found in ~/.ssh/config like:

Host remotegateway
User alpha
Hostname remote.gateway.com
# LocalForward 52340 192.168.0.28:22
# DynamicForward 2080
Port 443
IdentityFile ~/.ssh/id_remote_rsa

For those I simply connect by using "ssh remotegateway"

sshuttle works perfect for me with SSH keys.

I don't know of any (commandline) application, which uses ssh as
transport backend, which does not support SSH keys or SSH confguration
via .ssh/config

Alternate SSH ports should work via .ssh/config.

Should work. Does it not work for you?

Kind regards, Axel

You were right I can use sshuttle with just the a server name defined
in my ssh config file.

Now how can I do it from the command line without using a ssh config
file? Looks like I can pass the port number using "-r user@sshgateway:
443". But how can I specify a RSA private key from there?

Thanks

If your ssh setup is so complicated that you need to specify a
particular ssh key (rather than just using the same ssh key on every
remote machine) then you should just use a .ssh/config and cut your
losses.
