Hi,

one of the programs we installed recently needs access to internet and ports 2001 through 2005.
First, how would i check if these ports are already open or accessible on one of the server command lines and 2nd,  how would i open up these ports on a netscreen 5gt?  Thanks.

From the server out to the internet.  I know there is a command that lets you know what ports are currently open on a machine so was thinking of checking that first if you happen to know it for the command line.

telnet <destination-ip> <port #>

so to see if smtp is open on email server i would do the following:

telnet email.server.com 25
220 email.server.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.467

in the juniper if you have trust to untrust policy that allows source any, dest any and service any. then you dont need to do anything else

They said the software just needs access to the internet so by default doesnt all outbound traffic from internal network to internet get through no matter what port it uses? You only have to set up policy for specific ports if they are coming from outside correct?

Yes by default that is what is supposed to happen, but you can go on assumptions. If you post your policies we can tell you what may or may not be missing

Sorry got busy on something else for awhile, but looks like it is working since software is able to get out to internet and not problems so far so thanks for the help.  Just wanted to know for the future where i can go in the netscreen admin screens to print out my settings as you mentioned about the policies.  Thanks.
