accessing Sco Unix tthru cisco vpn

I have a problem with acessing Sco Unix thru a cisco vpn.
On internal lan i can ping the ScoUnix box and telnet into it. However when i vpn into the office i can ping and telnet widows and cisco devices but not the ScoUnix box.

internal lan is on /24
vpn users get address assigned on /24
gateway is

I think a route has to be added to the ScoUnix box for it to see /24.
i do not have experience with Unix so i would not know how to go about doing this.
please advise, thanks

on sco unix:
netstat -rn to show routing table
most likely route is missing on sco

please check if there is a route on SCO box:
  # netstat -rn
It should have a route for via

If not there, you will have to add it, using
  # route add   1

There should be a file named /usr/internet/etc/sco_ip/routes (being interpreted by /etc/rc2.d/S90iproute) into which static routes will have to get entered. Otherwise, the route will not get installed upon next boot.
If you have an older SCO version, the place to add the "route add ..." command is the file /etc/tcp instead.
