Question Fwbuilder slow down to my upload speed to zero !

Hi guys,

I just configured a fwbuilder for LINUX 2.4 (RedHat 9). The box has 3 interfaces.

Eth0 = External
Eth1 = DMZ (Web Server)
Eth2 = Internal

Now everything seems fine but when I uploading something from internal network (I have enabled ftp) , it’s connecting fast but slow down the download speed so fast. And get crashed the file that I was uploading.

Probably the issue is on the firewall, I did by pass the firewall then it’s uploading without an issue.

Please advise!

(If you need more information about the firewall, please request)

mmm... sounds strange to me.
I mean, as far as I know about packet layer firewalls, something works or not... it doesn't, stop working during the time.
I believe it's more likely to be a physical layer problem or something like that...
could you provide some extracts from your firewall?

Yes TheIrish, I have replaced internal network card. After that, everything is ok by now.

Now External, DMZ and Internal three interfaces packet filtering without an issue.

Thanks !
