If you really wish to understand how the tcp stack work
i've spent a good number of hours RTFMs, trying to make the best of a bad
situtaion: userland natd instead of kernel-space nat.
the only practical advice i found was to increase the maxusers kernel
option - we're already at 1024 (with plenty of ram to support it). other
advice was to have a st

I would like to use PPPoE with MPD in orderto connect
to a DSL modem by the way of Ethernet LAN. My freeBSD
version is 3.5 Release (it's out of mind to update it)
and the MPD one is 3.6 (I don't want use a user land
way for pppoe as ppp). But I have two problems.
First of all, the netgraph encryp
Hello all,
Thanks for the response.
I have attached the "tcpdump" collected at the receiver,
and "netstat -p tcp" at the sender as well as the receiver.
I run the tests on a isolated pair of machines (FreeBSD 4.3), connected
over a pair of back-to-back crossover cables and these
links are

first advise:
add more firewall rules so that any packets that YOU KNOW will not be
translated will bypass the natd..
i.e. make sure packets fromteh localhost are not sent to natd.
What throughput are you trying to NAT?
I've never seen it be an issue.

why are you requiring mpd and not ppp?
ppp can to pppoe too.
(however it would b egood to discover if there is a bug in mpd anyway.)

Hi all,
first of all, could you please cc any replies to me ? (I'm not on this

Last time I checked (around fbsd4.3) , I was unable to set the mtu of

that i was able to set the mtu of the gif device to 1500 (and saw that

I've been told that if you use ipf and ipnat, then you get the benefit of
kernel-space NAT. Have you investigated this to see how it compares to
natd/ipfw for you
