Hi
I am using verion 2.0.10 of Shorewall.
My configuration is as follows:
Eth1 dmz1
------------| __________
| |
|
Eth2 dmz2 | FIREWALL |------| INTERNET |
----------| | _______ | |__________|
| |---------| | ________ |
_______
Eth3 dmz3|-----------| | net | |----| | |
----------------------| |-----------| SIWTCH |-------| PROXY |
|-----------| | eth0 |________| |_______|
Eth4 dmz4| |---------|_______|
----------| |
|
Eth5 dmz5 |
------------|
In this configuration, if I connect directly to the switch in the diagram
above, and use the proxy, it is lightning fast (as it should be). Whenever
I connect on one of the interfaces behind the firewall
(dmz1,dmz2,dmz3,dmz4,dmz5) it is extremely slow.
The only thing running on the Firewall is the shorewall configuration files
and services needed to run that. It is a P4 XEON 2.8GHZ DELL Power Edge
2600 running SCSI and 1GB of RAM. The load averages is under 0.40.
Any Ideas?
Regards
Christo Louw

Turn off Shorwall ("shorewall clear") and try running tests between the firewall and the proxy. The output of "ip -s link ls" may help show where errors are occuring also. Also be sure that all firewall interfaces have the same MTU. - -Tom - -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.5 (GNU/Linux) iD8DBQFBk4koO/MAbZfjDLIRAhhlAJ9gjk5/7xPifBXHk5esnqmDsO1xJACfRTFd PJHLCgwYUgoSx+YgcC9w42A=yP/7 -----END PGP SIGNATURE-----

With the "shorewall clear" command I get the same results. Can it be
qdisc?
I have read somewhere that it is best to set a Dell''s Gigabyte card to
100
Full duplex then let it to discover what speed to use. Not sure though

Your server has broadcom cards on board. I had problems with the bcm5700
module under Kernel 2.4.20. I now use the tg3 driver that works with this
chipset, too. Please tell us kernel version/distribution you are using and
wich driver-module is loaded for the cards.
