I need to block UDP port 16470 on ASA 5510 for a trojan. I have got internet coming from ADSL interface and want to block data going from users machine to the ADSL interface on UDP 16470 so that i can find out which PC has the trojan. How can i set the access rules?
I have tried setting ACL on ADSL (outgoing rules) but it blocks the internet. I was wondering where to set access list to block UDP port 16470.
