Hi all
I have a SUSE linux box running 2.2.6 with ipchains/MASQ running. I
have within /etc/rc.config
in the Firewall & Masqeurading sections the proper items (all are not
included below)
FW_START="yes"
FW_LOCALNETS="192.168.0.0/24 24.112.x.x "
FW_INT_DEV="eth1"
FW_WORLD_DEV="eth0"
FW_ROUTER=""
FW_FRIENDS="yes"
FW_INOUT="yes"
MSQ_START="yes"
MSQ_NETWORKS="192.168.0.0/24"
MSQ_DEV="eth0"
MSQ_MODULES="ip_masq_cuseeme ip_masq_ftp etc"
******************************************************
and /etc/fw-friends contains the said reserved class C clients:
192.168.0.1
192.168.0.2
192.168.0.3
/sbin/init.d/masquerade status returns:
IP masquerading entries
ipchains -L returns:
Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
target prot opt source destination ports
user_msq all --- 192.168.0.0/24 anywhere n/a
Chain output (policy ACCEPT):
Chain user_msq (1 references):
target prot opt source destination ports
MASQ all ------ anywhere anywhere n/a

On internal network with Linux box with two NICs that show via
ifconfig:

Finally route -n returns:

I cant see why one cannot ping an internal client
(e.g. win95 with TCP IP set as 192.168.0.2/255.255.255.0 and gateway as
192.168.0.0/192.168.0.1 or gateways set singularly), or ping from
client to linux box.
This on on baseT ethernet and hub/cables work under NT.
Any recommendations and/or ideas as to what is causing this problem
would be greatly appreciated.
Thanx for your time
Mac
