Oh! Yeah When you use ipmasqerading, redhat by default does not turn on some modules.

I manually start the modules in /etc/rc.d/rc.local

# SuSe by default adds a ip_ modules for general clients to the kernal at start.
# Redhat does not.
# add ip forwarding of general clients
# /sbin/modprobe "module" modules are found in /lib/module/kernal_#/ipv4
/sbin/modprobe ip_masq_ftp.o
/sbin/modprobe ip_masq_irc.o
/sbin/modprobe ip_masq_raudio.o
/sbin/modprobe ip_masq_vdolive.o
/sbin/modprobe ip_masq_cuseeme.o
/sbin/modprobe ip_masq_quake.o

I also place my other generic ipfwadm commands here.

# added by taw for ipforward admin.

# By default DENY all services
/sbin/ipfwadm -F -p deny
# Flush all commands
/sbin/ipfwadm -F -f
/sbin/ipfwadm -I -f
/sbin/ipfwadm -O -f

# Forward email to your server
/sbin/ipfwadm -F -a accept -b -P tcp -S 0.0.0.0/0 1024:65535 -D 192.168.1.1 25
# Forward email connections to outside email servers
/sbin/ipfwadm -F -a accept -b -P tcp -S 192.168.1.1 25 -D 0.0.0.0/0 1024:65535

# Forward Web connections to your Web Server
/sbin/ipfwadm -F -a accept -b -P tcp -S 0.0.0.0/0 1024:65535 -D 192.168.1.1 80

# Forward Web connections to outside Web Serve
/sbin/ipfwadm -F -a accept -b -P tcp -S 192.168.1.0 80 -D 0.0.0.0/0 1024:65535

# Forward DNS traffic
/sbin/ipfwadm -F -a accept -b -P udp -S 0.0.0.0/0 53 -D 198.168.1.0/24

etc etc.

Hope this helps... Don't use net whatever.
