Tárgy: 2 questions: 1., ipfwadm, 2., local net with rtl8139

hi!

1., I' d like to use ipmasquerading to share the internet,
but i have
problem with it. I have installed the following modules into
the kernel

  IP: Netfilter Configuration  --->
    <M> Connection tracking (required for masq/NAT)
    <M>   FTP protocol support
    <M>   IRC protocol support
    <M> IP tables support (required for filtering/masq/NAT)
    <M>   Packet filtering
    <M>   Full NAT
    <M>     MASQUERADE target support
    <M>   Packet mangling
    <M> ipchains (2.2-style) support
    <M> ipfwadm (2.0-style) support

(certainly i don' t use the last two).

All other modules can be loaded with success.
I use 2.4.26 kernel, and if i load all modules, i got this:

"
router:~# lsmod
Module                  Size  Used by    Not tainted
iptable_mangle          2208   0  (unused)
ipt_MASQUERADE          1952   0  (unused)
ip_nat_irc              2752   0  (unused)
ip_nat_ftp              3616   0  (unused)
ip_conntrack_irc        3296   1  [ip_nat_irc]
ip_conntrack_ftp        4128   1  [ip_nat_ftp]
iptable_nat            22516   2  (autoclean)
[ipt_MASQUERADE ip_nat_irc
ip_nat_ftp]
ip_conntrack           30452   2  (autoclean)
[ipt_MASQUERADE ip_nat_irc
ip_nat_ftp ip_conntrack_irc ip_conntrack_ftp iptable_nat]
iptable_filter          1728   0  (autoclean) (unused)
ip_tables              14560   6  [iptable_mangle
ipt_MASQUERADE iptable_nat
iptable_filter]
8139too                13376   1
ne2k-pci                4416   1
router:~#
"

eth0 is the interface to the internet, and eth1 is for the
local net.

>>>The problem come, if i try to use the following command:<<<

"
router:~# iptables -A FORWARD -i eth0 -o eth1 -m state --state
ESTABLISHED,RELATED -j ACCEPT
"

then i got this error message (error code: 1):
"
iptables: No chain/target/match by that name
"

I tried to loose the problem with google, but nothing could
help. Certainly
i made these:

"
echo "1" > /proc/sys/net/ipv4/ip_forward
echo "1" > /proc/sys/net/ipv4/ip_dynaddr
"

Distro: debian

-----------------------------------------------------------------------

2., the second problem is, that i have in this router
machine two
ethernetcard (rtl8029, and 8139). the 8029 works fine, but i
use 8139too
driver for the other one. If i try to copy(ftp) _to_ the
router, everything
works fine with about 2MByte/s (the router is a PI 100MHZ,
so it' s good for
it), but in the other direction (from the router to another
machine) i can
copy only with 2-300KByte/s.

In the kernel (2.4.26) i compiled this as modules:
"
   <M>     RealTek RTL-8139 PCI Fast Ethernet Adapter support
",
and compiled these into the kernel:
"
Use PIO instead of MMIO
Support for uncommon RTL-8139 rev. K (automatic channel equ...
"

I tryed all combination of the last two.

The cabel length is about 20m.

Both of the Distros are Debian;

Thans very much for your help.
