My server runs Redhat 7 with a compiled 2.2.18 kernal

I have been very happy with it but now I want to take advantage of bandwidth control that is built into the 2.4 series kernal

My question is will my firewall ruleset be hard to change to the new iptables. And will the Mods (eg. ip_masq_quake ) work with the new kernal

here is my firewall script:-

#Clears the firewall rules
/sbin/ipchains -F

/sbin/depmod -a
/sbin/modprobe ip_masq_ftp
/sbin/modprobe ip_masq_raudio
/sbin/modprobe ip_masq_irc
/sbin/modprobe ip_masq_quake 26000, 27000, 27910, 27960
/sbin/modprobe ip_masq_cuseeme
/sbin/modprobe ip_masq_vdolive
/sbin/modprobe ip_masq_icq
