i followed these instruction to the point Comodo Help and still i see going thru my application even they are not in the list
what i want to do is i have the application which runs with udp protocol its a server application and there is client application in the clients computer
client have to talk to server application in order gain info from it and they both use UDP protocol
all i got for the application is application user access list which is no way for me to block unauthorized user to connect
well comodo firewall has the Application Rules which will filter out the ip address and from there you can define the mac address each and ever one of the mac address entry before makes it to the application since the data flow coming in in UDP format why i am still seen the clients in the application server ??
i was in the impration this is the reason this option was there here is the instruction portion where its says we can do it
can any buddy help me on this
TIA
Apologies, I’m not sure I really understand what you’re trying to do. It sounds like:
a. You have an application running on a server?
b. You have a client that needs to connect to the server application?
c. The protocol use is UDP?
The image you’ve displayed is for loopback, which is a system wide rule for allowing process internal communication over TCP and UDP for 127.0.0.1. This rule is only necessary for applications/processes that make use of this internal communication.
If you need to allow an application to connect to a specific server, you will need to create a specific rule in the firewall of the client. if the server is also running a firewall, you will also need a rule to allow inbound communication from the client. For example, on the client:
Application name - acme.exe
Action - allow
Protocol - UDP
Direction - Out
Source Address - ANY
Destination Address - The server MAC/IP Address
Source port - ANY unless the application uses a specific port
Destination - The port used by the application
On the server:
Application name - acme.exe
Action - allow
Protocol - UDP
Direction - In
Source Address - The MAC/IP address of the client
Destination Address - ANY or the MAC/IP address of the server
Source port - ANY unless the application uses a specific port
Destination - The port used by the application
Depending on how you’ve configured your Global rules, you may also need to add a Global rule for this inbound communication.
