[pptp-server] pptp masquerade document needed for 2.4.x basedfirewal

[Craig Morris]

Thanks for your response,

Here is the output from modprobe:

modprobe -v iptable_nat
/sbin/insmod
/lib/modules/2.4.3-12/kernel/net/ipv4/netfilter/ip_conntrack.o
Using /lib/modules/2.4.3-12/kernel/net/ipv4/netfilter/ip_conntrack.o
Symbol version prefix ''
/lib/modules/2.4.3-12/kernel/net/ipv4/netfilter/ip_conntrack.o:
init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
/lib/modules/2.4.3-12/kernel/net/ipv4/netfilter/ip_conntrack.o: insmod
/lib/modules/2.4.3-12/kernel/net/ipv4/netfilter/ip_conntrack.o failed
/lib/modules/2.4.3-12/kernel/net/ipv4/netfilter/ip_conntrack.o: insmod
iptable_nat failed

And here are the currently loaded modules:

[root at shockwave init.d]# lsmod 
Module                  Size  Used by
ne2k-pci                4096   2  (autoclean)
8390                    5632   0  (autoclean) [ne2k-pci]
ipchains               27648   0  (unused)

I'm still using ipchains instead of iptables, although I'm not sure if
it makes any difference.

Thanks,

Craig Morris
