But,it doesn’t work 🙁 RDP protocol is still blocked. although allowing ICMP on the L2 works… How do I allow outgoing connections application wise like allowing Windows Remote Desktop (port 3389)? Thanks November 5, 2008 at 6:46 pm #47102 imported_fulvioParticipant L7 filters can be used to drop and shape the traffic. You should never use them in ACCEPT rules. This is because the L7 filters can need more than one packets to intercept a protocol, but if you drop the first …. Regards Fulvio November 6, 2008 at 3:14 am #47103 uniquegodwinMember But,i want to block all traffic by default and allow only required traffic ….since blocking all L7 applications one by one will be very hard. Is there any way to block all traffic and allow only the required L7 ports? Thanks Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
