You should also consider a used speedstream 5100b, 4100 or 4100b dsl modem one may be a better fit
Well, I still have a Speedstream 4100. That started the whole issue, because the Speedstream doesn't let outbound tunneled IPv6 packets through. The Motorola does.

Why is the ping so important to you

That also has to do with IPv6. HE's IPv6 tunnelbroker (»www.tunnelbroker.net/) tries to ping the IPv4 address to verify the tunnel.

So.....the speedstream 4100 only blocks outbound IPv6 packets

The motorola 2210 blocks icmp pings

The Speedstream blocks outbound IPv6 packets encapsulated in IPv4. I didn't even try to send IPv6 directly...
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

A 15 second lease time means the client is always renewing the lease.........not a good thing

I hope you're able to find what you need
