Hello

    i am still having trouble with this Mandrake setup.
I am attempting to setup IP Masqurading through IP Chains .
I have had this configuration previously running on a RH 5 box, and decided
to upgrade.

I have used the PMFirewall program to create the firewall and
masqurading rules.  From the Linux box, I can ping both the internal
network and the internet. However, from a workstation running win98, I
can only ping the linux box.  When I attempt to ping the intetnet, I get
the following (thanks to tcpdump)

13:05:47.551865   192.168.67.20 > 220867-db: icmp: 192.168.67.20 udp
port unreachable [tos 0xc0]

I have have removed all of the pmfirewall rules and tried a very basic
ip chains rules as follows

echo "1" > /proc/sys/net/ipv4/ip_forward
/sbin/ipchains -P forward DENY
/sbin/ipchains -A forward -s 192.168.67.0/24 -j MASQ

i realize that this is probablu the simplst ip masq rules that can be
set, but I still get the same message in tcpdump

I am using 2 network cards, 1 connected directly to my cable modem
(which gets it's ip via dhcp)  This is eth0
The second one is connected to my local network with a static ip of
192.168.67.20
    The win98 workstation has a static ip of 192.168.67.2
    On the linux box, the DNS server is pointing to the DNS server from
my ISP
    The default gateway is also pointing to my ISP's gateway
        The above settings are exactly the same as what I was running on
the RH5 box, but I was using ipfwadm for my rules
