As the title suggests, those of you not familiar with networking may
want to skip this over.
I have two questions. One is FreeBSD specific the other is not.
1) I have accumulated a large amount of experience with the Linux
implementation of NAT, a kernel-land trick they call "IP Masquerade".
I am aware that FreeBSD, and presumably the other BSDs offer similar
functionality in the form of a user-land "NATd". I need to know if it
is as functional as the Linux implmentation? The Linux implementation
has "helper" modules for troublesome protocols such as ftp, irc, icq,
even Quake (I do HalfLife though :). Will these work across a BSD box
doing NAT?
2) This one is a bit lengthy, involves ASCII artwork, and is
network-general, though I hope it will apply to FreeBSD or any free
'nix.
10BaseT Ethernet
A (WinNT)
|
ADSL --- HUB --- B (Win95)
|
C (whatever)
All the machines in this scenario pull IP off a DHCP server over the
ADSL.
Transfers from any local machines, such as A sending a file to B
cause the ADSL modem to go nutzo. The transfer is also very slow (by
ethernet standards). Just pull the ethernet wire from the ADSL modem
and it speeds up DRAMATICALLY. I am looking at putting a 'nix box on
this network, and if I can make it act as a switch* between the ADSL
modem and the rest of the network, than so much the better. The only
"switch" I have seen or have experience with is a 3Com SuperStack ][
(I think), which is more than a little bit out of my budget. Can
anyone suggest a cheap piece of network hardware or a 'nix OS that
can do this?
* I understand a "switch" to be a device that examines the MAC
address of machines on the network, and only passes packets on to
another interface if such is necessary. This would mean packets from
A to B don't need to go over the modem, and would not.
If you reply to this, PLEASE snip appropriately, I hate seeing
>>>>>>>> all over the place :)
