Re: [Modem] Motorola 2210 doesn't respond to ping
said by jfeise  :So, it seems that ICMP is blocked. Is there a way around that, other than bridge mode (which I don't really want to do)? The modem in the other thread has a different software version 7.7.3r5 If the modem has been set to drop icmp pings the only workaround is bridge mode
There are some other ways to access the modem when its in bridge mode |

I even tried the 7.7.3r7 Southeast firmware (which has some other issues), but none of them responded to a ping from the outside.

As I said, bridge mode is not what I want to do. The last time I did a PPPoE setup on my Linux box was about 10 years ago when I had an ISDN line, and it was a bit of a pain, if I remember right...
Accessing the modem is not the major issue, the major issue is that in bridge mode I can't just connect another computer to the modem (for example, for my testing I just plug my netbook in), I would have to install PPPoE handling on any computer that I want to connect.
I talked with level 2 support from AT&T, and the guy recommended a 2-Wire 2701, but that has a router built-in (and useless wireless without WPA), as far as I can tell. I don't know if the 2-Wire can be set to give one computer on the LAN side the WAN IP address. |

It may be that the setting you need is labeled with a term other than "ping" and its overlooked
Can you give more details about your "(which has some other issues)" comment
I think the "bellsouth" gui is your last option before bridge mode or replacing the modem

The 2wire 2701HG-B supports wpa-psk and wpa2-psk authentication it also has a "dmzplus mode" where one computer shares the public ip address |

It kept renewing the 192.168.1.64 address all the time. But I was able to get out to another machine on the Net, and try the ping from there.
While the bellsouth interface has more options, I didn't see anything ping or ICMP related.

Thanks for the info. Looks like it fits my requirements then. I won't use the wireless, though, since I already have an internal wireless WPA setup. |

The motorola 2210 blocks icmp pings |

But it let inbound tunneled IPv6 packets through, as tcpdump showed.
Another modem I tried was a D-Link 2320B. Ping worked, and it gave the WAN IP to the local computer, but with a DHCP lease renewal time of 15 seconds, not changeable of course...
All I need is a DSL modem that lets all packets through, and allows me to get the WAN IP address on the local computer, with a reasonable DHCP lease time.
Not too much to ask, I think  |
