In some informal experimentation, I noticed -
- the PPP negotiation works okay - user gets authed, IP address, DNS
servers, default route, etc.
- I can slip a small amount of data through initially; i.e. one ping
packet or one DNS lookup
- then the infamous "Waiting for reply. . ." on the user side, or
timed-out pings, etc.
- I can [almost] always still ping the pm3 directly, but nothing beyond
it. I'd believe it's a routing problem except 1) 1st packet(s)
transmitted ok, and 2) other users work with the same routing table and
the same dynamic IP's
This is _release_ software, not beta.
