The easiest way to do is to su to your admin account and then use sudo as you have been doing.

If you have to create the tunnel frequently, then the best thing to do is edit the suders file and give your non-priviledged user permission to run the exact command you use to create the tunnel. BTW, you have to use visudo since you can’t do it with another editor. Don’t give your normal user account, full sudo priviledges since that would make it an administrator account (almost).
