This is the best answer. Jump through the bastion host. Then you can
use the ssh-agent on your desktop.

Answering this directly though is the "keychain" package. Install it.
Then put this in your .bash_profile or .xsessionrc or the other
appropriate environment file.

    keychain -q
    . $HOME/.keychain/$(hostname)-sh

That will do all of the bookkeeping to start an ssh-agent if it is not
running or to share an ssh-agent that is running.

Hint: This also works to allow cronjobs to have access to a shared
ssh-agent.
