cannot ssh from outside network

[Paula J. Lindsay]

Hi,
I have a redhat 9 box. 

I tried to connect to the redhat 9 box from a machine outside our network and got the following...
      101 worf: ssh -l spooner 137.131.252.71
      ssh_exchange_identification: Connection closed by remote host
      
      And the following packet capture from inside of our firewall shows that born receives the connection and then refuses it with a Fin packet...
      15:51:13.740835 192.42.82.56.1401 > 137.131.252.71.22: S
      15:51:13.744082 137.131.252.71.22 > 192.42.82.56.1401: S
      15:51:18.821897 137.131.252.71.22 > 192.42.82.56.1401: F 
      
      A connection attempt from within our network is successful.  Maybe this machine is treating hosts from outside of our 137.131 IP space differently?
      Can someone help me?
Many thanks in advance.
Paula
