Currently we have a pix 515 firewall that is used for a certin app called Five 9 ( a voice over ip thing )
 any ways some of our users are learning that they can route their pc across this connection and get  unrestricted access to the web. what i want to do is change the config to allow only the traffic to the five 9 app across this and route all other traffic to our other gateway witch is
10.1.5.1 mask is 255.255.255.0
 the only traffic that should go across is to this subnet
72.5.65.0 mask 255.255.255.0 <--- the five 9 servers.
 and to allow Ping and Trace Route for Trouble shooting.
  Please help Thanks  ...
   Here is the current config of the Pix...

>access-list inside permit ip any any
You have to change the inside acl:

no access-list inside
 access-list inside permit ip 10.1.5.0 255.255.255.0 72.5.65.0 255.255.255.0
 access-group inside in interface inside

Done.
