impasq

[Joakim Roubert <jokke@df.lth.se>]

Hi!

I started kicking on my ipmasq again, to make it work.
Network works fine between my two computers, but the masquerade doesn't;
that is, the internal computer cannot reach "outside".

First, lets see what I've got in my 2.4.20 kernel.
According to the documentation, I've compiled support for:

     * CONFIG_NETFILTER
     * CONFIG_IP_NF_CONNTRACK
     * CONFIG_IP_NF_NAT
     * CONFIG_IP_NF_TARGET_MASQUERADE

Addtionally, the documentation also says I should have:

     * CONFIG_IP_NF_TABLES

...but I can't find it in my /usr/src/linux/.config; here I have this
though:

CONFIG_IP_NF_IPTABLES=y
CONFIG_IP_NF_ARPTABLES=y
CONFIG_IP6_NF_IPTABLES=y

Could this be my bug?
If not, the story goes:

octavia:~$ ipmasq -d
#: Interfaces found:
#:   eth0       194.47.216.24/255.255.254.0
#:   eth0       194.47.216.24/255.255.254.0
#:   eth1       10.0.0.1/255.0.0.0
#: Disallow and log packets trying to come in over external interfaces
#: from hosts claiming to be internal
#: Accept dumb broadcast packets on external interfaces
#: Accept incoming packets from external networks on external interfaces
#: Masquerade packets from internal networks
#: Deny and log packets attempting to leave over external interfaces
claiming
#: to be for internal networks
#: Allow dumb broadcast packets to leave on external interfaces
#: Allow packets for external networks leave over external interfaces
octavia:~$

The internal computer attached to eth1 has the same configuration as
before, when I successfully ran masquerade on a RH system.

Does anybody have any ideas on this, or does anybody know where I can find
the most recent and valid documentation on this field?

Regards,
