Hey Everyone,
I'm looking for a little clairification here:
--
I beleive this isn't possible though this is hazy to me. The reason
why I say it is hazy is that there are cablemodems out there that
receive on cable but transmit back on a analog modem. Obviously, these
two connections will have different IP addresses.
These hybrid cable/analog systems are reported to WORK under linux though
I dont' know quite why. The reason why I'm skeptical is that when a packet
comes in on your cablemodem, the sending server is expecting ACKs from
that same IP. Yet, on this setup, the ACKs come back from the analog modem
with a different IP address. Why doesn't the remote server complain about
this?
