ssh from mac to linux

I am still a beginner with using terminal. I am trying to ssh from my mac at home to a linux at my university. I am using VPN to connect to the network. When I ping the IP address of the computer I want to connect to it responds. I can connect when I am on campus, but not when I'm off. When I try ssh -v username@IP this is what I get:

debug1: Reading configuration data /etc/ssh_config
debug1: /etc/ssh_config line 20: Applying options for *
debug1: Connecting to 10.36.0.250 [10.36.0.250] port 22.
debug1: connect to address 10.36.0.250 port 22: Operation timed out
ssh: connect to host 10.36.0.250 port 22: Operation timed out

Running traceroute gives

traceroute to 10.36.0.250 (10.36.0.250), 64 hops max, 52 byte packets

Any help would be much appreciated.
