Re: HEADS UP Gentoo installfest - iptables RH9

[InfoHelp]

Thanks for the checklist Nick, & the facility Rob,

A final preparation for me to use Gentoo on my laptop will be having my 
RedHat9 desktop share its dialup Internet access, for future emerge work 
at home.

Pings ok: RH desktop 192.168.0.254 < -- > 192.168.0.1 laptop Suse (which 
accesses Net gateway 192.168.0.254  fine when the desktop is booted to 
Win2K)

I've got the desktop script in place from:

http://www.e-infomax.com/ipmasq/  3.4.1. Configuring IP Masquerade on 
Linux 2.4.x Kernels
<rc.firewall-2.4 START>

as /etc/rc.d/rc.firewall-2.4
I edited 3 lines only:
EXTIF="ppp0"
INTIF="eth0"
$IPTABLES -t nat -A POSTROUTING -o $EXTIF -s 192.168.0.1/32 -j MASQUERADE

& run it from /etc/rc.d/rc.local

Initialisation flashes by apparently ok, but the log file for what it 
says isn't dmesg, & I haven't found it anywhere else to double check 
success.

I've set RH Security Level to No Firewall (before this Lokkit had a  set 
of rules going)  & now have:

[EMAIL PROTECTED] root]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
I tried & found that:

[EMAIL PROTECTED] root]# IPTABLES -t nat -A POSTROUTING -o $EXTIF -s 
192.168.0.1/32 -j MASQUERADE
-bash: IPTABLES: command not found

while

[EMAIL PROTECTED] root]# iptables -t nat -A POSTROUTING -o $EXTIF -s 
192.168.0.1/32 -j MASQUERADE
Warning: wierd character in interface `-s' (No aliases, :, ! or *).
Bad argument `192.168.0.1/32'
Try `iptables -h' or 'iptables --help' for more information.

But am struggling to decrypt this  :-/  ... try all lower case?

Must be close though.. will try the alternative /etc/rc.d/init.d/ method 
while awaiting other advice.

Thanks for any guidance,

Cheers

Rik

OK please note;

1. All punters should do some preparation, viz:

1.1 read and re-read the handbook at http://www.gentoo.org/doc/en/handbook/ .
Robert has printed out 6 copies - one each - so contact him if you hate
reading off the screen.

Have been reading online, & the laptop has Suse running quite 
successfully for comparisons. Partition ready.
