In yours, the authentication pairs are the client and domain.com; and the client and 192.168.1.20 (via the tunnel). In mine, the pairs are the client and domain.com; and domain.com and 192.168.1.20. This makes a difference if you're using keys (not passwords): in yours, you would have both keys on the client machine, whereas in mine, you'd have the key for domain.com on the client machine, and the key for 192.168.1.20 on domain.com. You can omit the -t if you're using keys; you need it if 192.168.1.20 prompts for a password.
