Hi there! first thanks for your time to read this post.

I´m running KWF 6.7.1 on windows 2003 server, with 6 eths. (1 onboard 5 pci 1gpbs)

Actualy I don´t have to mutch trafic (i´m trying it, reemplacing 3 linux server with this kwf..)

I was running ok by 1 week, today monday the dhcp server stop asigning IPs.

I installe wireshar (network audit tool) and I see that the request goes to the server, but the server never answer.

In the Asigns ("asignaciones" in spanish) tab in DHCP server I see the mac of the pc and that kerio asign IP, but it never respond to the client.


at the warning log I see:

[05/Jul/2010 09:58:33] (1012) Particular network traffic lost or was modified by conflicting software or KWF driver disabled on some interface!

I try reinstaling KWF to "resinstall" the driver too, but Its same problem.

I Create hundreds of rules trying everythin, allowing trafic from "any" or "lan card" to "any" or "firewall" at DHCP/BOOT and i try also port 63 UDP.

The connection comes, the KWF asing IP in the table but never respond to the client.

now I´m start DCHP server from W2k8 on my net until I repair this problem.

Any Idea??

Thanks again and sorry for my poor english

I presume you have al different IP segments.
Exampe
LAN1 192.168.1.0/24
LAN2 192.168.2.0/24
etc, etc
and not
LAN1 10.0.1.0/8
LAN2 10.0.2.0/8
Because then your network is still one segment.

Also could be the problem the rules.
Don't forget to put in every LAN rule the "Firewall".
If you forget this one then no IP will be deliverd

Hi ictandme, Thank you very much for your interest and reply Smile

Well, I know that i have some subneting problems, but everything was working well until yesterday.

I upgrad to Kerio Connect and now everything is working again. I got same problem now with other server that I got in other bulding. I Suspect that a W2k3 windows update install something...

Anyway, now is working nice again. I will try it this days, if I got a problem I start DHCP server from a windows 2k8... and post the problem again Very Happy

Thanks again for your help.
