It's a larger issue than that. Backups through a firewall are not
supported in TSM (officially).

Two suggestions:

1. Use prompted scheduling, rather than polled. This allows you to
specify the TCP port used for server-client communication. (The
default for prompted schedules is 1500.) Keep in mind that if you set
up multiple machines in this manner, and they are performing
concurrent backups, they'll all be using the same port, thus impacting
throughput.
2. Make sure that the proper TCP ports are open. The defaults are 1500
and 1501; they need to be open to traffic in both directions.
