I need to know whether this will also prevent forwarding of > Source Routed IP Packets. the IP_FORWARDING option is deprecated. Use sysctl 'net.inet.ip.forwarding' to control this behavior. FreeBSD throws away Source-routed packets unless you enable sysctl `net.inet.ip.accept_sourceroute' and maybe 'net.inet.ip.sourceroute'. See `man sysctl' for information on using the sysctl interface.
