Allow peer-to-peer (P2P) file sharing programs with ISA Server 2006

Most people install ISA Swerver specifically to stop this sort of traffic - first time i have ever been asked on how to 'allow' it....

open the ISA gui - select monitoring - logging - click on start query
try the connection from a client - what do you see appear in the ISA log window as denied?
make a note of the ports/protocols being denied and let me know.

Hello keith_alabaster,
I know u r surprised for my reques but i just apply this rule for 1 client not all clients , that's all,

-------------------------------------------------------------------------------------------------------------------
I hope u got what u asked
Thanks in advance

Would have expected it to state udp or tcp also but may be not; its difficult to tell sometimes. Because of that you may need to play a little here.

Open the gui. Select the firewall policy then right-click it and select new - access rule.

Give it a name
Select allow
Select selected protocols - click add
select new - user-defined and add the ports that you want to allow for example
tcp 4672 - 4672
tcp 2100 - 2100
etc
select the new ports you have created for the rule and then finish the access rule - from internal & local host to external in the normal way.
Apply the policy

retest and check the logs again. You will need to fine tune this yourself as I do not know if all of these are tcp or udp or whatever....

PS - make sure the rule also includes any other ports that may be required for the user such as http, https etc.
