backup computer over wan/lan

I've search and wasn't able to find answer to this specific question....

I have a backup server in location A, and would like to backup a Laptop in location B to a desktop in location B.

the backup works howerver it went snail slow at 2.00 MB/min.

I was hoping that the agent would handel the backup and stay on the LAN, but it apears it is taking the data over the WAN and back to the desktop.

is there any chance or way of speeding this up, maybe tweaking the agent, or a setting in Backup Exec?

thank you for your help.
