Kerio may be the best bet but IIRC it's not supported either- but with all the people who still use kerio I would suspect you'll find answers to any issues you may have. I think you could still use an older version of ZA, there's a fair number of people that use ZA 6. So, same with kerio, I think you can find answers to issues you may have in forums like here. Today I read somewhere that Symantec had purchased Sygate. Specifies for the IP filter driver to immediately return the drop response to the IP stack.
IP should drop the packet. Specifies for the IP filter driver to filter packets and return the resulting response to the IP stack. The filter hook returns this pass response if it determines that it should not process the packet, but should allow the IP filter driver to filter the packet. Although DDK documentation only includes these 3 values, if you look into pfhook. I suppose this value corresponds with dropping the packet and informing source for errors with an ICMP packet.
As you can see in the definition of the filter function, the packet and its header are passed as pointers. So, you can modify header or payload and then forward the packets.
If we change destination address, IP routes the packets. In my implementation, the filter function compares each packet with a list of rules introduced by the user application. You can see this in my source code. In the first version of this article, I included a simple example and -- because some people requested me to help them to develop real applications -- I updated it with a more complex one. The new example is a little packet filtering application. With this new program, you can establish your filter rules as you can do in some commercial firewalls.
If It doesnt have a firewall then how do i open port or allow certain program to run with no port restrictions?? Windows doesn't have built in firewall. You should use third-party products, like Zone Alarm, Kerio, Comodo etc. Red Flag This Post Please let us know here why this post is inappropriate.
