Thanks for the instructions.
Nothing seems to get through:
--------------------------------------
[tim@helen ~]$ ping anghiari.homelinux.com
PING anghiari.homelinux.com (79.46.6.203) 56(84) bytes of data.
--- anghiari.homelinux.com ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2000ms
--------------------------------------
--------------------------------------
[root@alfred tim]# tcpdump -l proto \\icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes
--------------------------------------
So I assume the modem is rejecting the ICMP packets.
As I said, I don't see anything about this
in the modem documentation or on the modem web-site.
