Which line must be added in the /etc/ipf/ipf.conf firewall configuration file in order to implement thesechang
The network in your company is divided into different subnets. All Solaris 10 OS servers on your network have Solaris IP Filter firewall enabled with a default policy rule that blocks all incoming connections.
One subnet, with address space 10.1.1.0/24, has a server named sys-x with the IP address 10.1.1.100/32.
Due to changes in your network, the sys-x server must accept connections to its X:0 to X:9 terminal ports only from the 10.1.1.0/24 subnet.
