I want to get hands on experience of using iptables, DMZ firewall, DHCP firewall, etc.for which Tutorial says I need to compile kernal with following options OR as modules :
 

  • CONFIG_NETFILTER

  • CONFIG_IP_NF_CONNTRACK

  • CONFIG_IP_NF_IPTABLES

  • CONFIG_IP_NF_MATCH_LIMIT

  • CONFIG_IP_NF_MATCH_STATE

  • CONFIG_IP_NF_FILTER

  • CONFIG_IP_NF_NAT

  • CONFIG_IP_NF_TARGET_LOG

I have installed Redhat Linux 8.0 on server machine which by default installs iptables 1.2.6a.

Do Redhat 8.0 install all these modules. How to check whether these modules are installed or not. 

Thanks


The stock Redhat kernels load these routines as modules. Run: /sbin/lsmod to see which modules are currently loaded. Note that the module name is not going to be the exact same name as the kernel option i.e.  if kernel option CONFIG_IP_NF_CONNTRACK is loaded as a module it will be loaded as module ip_conntrack.
