RCF Linux Firewall (rc.firewall) is a firewall software based on ipchains. It helps protect a system from unauthorized access and provides network security measures.
rcf firewall supports unlimited public, private (masqu'ed), DMZ, and MZ (non-masqu'ed) interfaces along with their respective subnets. Its access rules are well-defined per interface and dmz/mz server "clusters". Furthermore, the firewall is compatible with Red Hat, Slackware, Debian, Linux Router Project (LRP), and other distributions.
rcf Linux Firewall has received several updates, which include the contribution of 260-spop3-servers, 220-winvnc-servers, 620-arcserve-hosts, and netstorm (online game) modules. Additionally, the firewall has seen the resolution of several issues including a typo in 530-snmp-clients, fixed cluster handling in 030-pptp-clients and 030-pptp-servers, patched service_rules.sh to allow private IPs on DMZ interfaces, added missing rules that allow traffic from public interfaces to DMZ. It has also added the --refresh-interfaces command line option and fixed the jump rule problem which prevented private IPs from connecting to public interface IPs.
Overall, the rcf Linux Firewall is an excellent choice for those seeking a reliable and efficient solution for network security. Its numerous features and regular updates make it a top contender in the firewall market.
