Re: ping problem ...

The router is connected to the same system.

$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

Also, tell us a bit about your network. Where, for instance, is
192.168.1.1 in relation to the system you issue the ping on? Is it the
same system, or a different system.???

OK, so you send pings out, but you don't get a ping response.

It's not your /etc/hosts nor your /etc/resolv.conf. Both of those files
work with hostname-to-ip address mappings, and since you are pinging by
IP address, neither of those files is involved with the ping.

It sounds like a routing problem of some sort.

One further thought. It could also be the results of a firewall
blocking pings. Do you run a firewall? Does rp-pppoe run the firewall
for you? What do your firewall rules look like? Show us the output of
/usr/sbin/iptables -L -v -n -t filter
both with ping working and with ping failing
