Re: error pinging LAN


LC said:
Hi,

I have a router build using FC4. eth0 is connected to the modem, eth1 is
connected to the switch. I use roaring penguine to connect to the
internet with success. Windows boxes in the LAN are also connected to the
switch to gain internet access via the router. I had been running this
setup for 2 weeks and suddently it failed. The connection to the internet
can be established, but it seem that there are some errors in the LAN. If
i try to ping local machine of the lan, it tells me "ping: sendmsg:
Operation not permitted"

this means ping reguest are being dropped by your iptables.
check your iptables for lines like:
-A INPUT -s "your lan ip's/CIDR" -j DROP
-A OUTPUT -d "your lan ip's/CIDR" -j DROP

remove the said lines..


Can anyone tell me what happened?

best regards
