There was a discussion here lately about the first packets being
dropped (or strictly speaking not being answered to correctly)
which seems to apply to this case. Packets being generated
when the connection is established get all the params right
and cause no trouble.

That's when the DNS query is handled locally and the HTTP requests
causes the first packets to go out (and trigger dialing, which
does a renegotiation of the addresses and invalidates the source
address the packet already carries).

That's the prerequisite to these kind of problems :)

Then the DNS query triggers dialing and experiences the problem.
The HTTP request sees an established connection. It always turns
out to be the same scenario. The solution to this is the dynip
patch (available for Linux, at least) which queues the triggering
packets and resends them with the current IP address after IPCP
negotiation took place.
