It "never" makes it back? Your subject says "intermittent connections,"
so does it never work, or does it sometimes work, sometimes not? When
it does work, what's different from when it doesn't?

Is your kernel compiled with the option to masquerade ICMP? You'll
never see a ping response unless this is so.

Then you are not seeing the MTU problem.

Use "ftp -d -v" to show verbose information. See where the protocol
breaks down.
Can you just "telnet" to a site? Does it work, or not?

I don't know, but I doubt it. You communicate with the DSL modem via
ethernet, and the MTU for ethernet is 1500.
