Lan lost connection

Hi,
any 30' the firewall "Ghostwall v.1.150" block my lan, like if my lan lost the connection (I need to work with no IP address).
I resolve my problem just click to "allow all", so I can obtain a new Ip, and I'm connected again.
I'm connect directly to the router and my OS is WinXpPro32
Tnx to all for help me!

 

You have something blocked that need to be allowed. However no one can help unless you provide more information. Can you post a pic of you're rules config or at least a list of the rules?

However if your Local LAN is 192.168.0.1-253 you can put the rule in the pic to allow it through or adapt the rule to your "Local LAN IP's" If you are using static IP's on you're LAN then you can create a rule for each PC to interact with each others it would take more work but it also would be better secured...

 

Also you may have accidentally modified or deleted the DHCP1 Rule which allows you to handle the Renewal from the "Domain Host Controller Protocol" (Automatically Issues and Renews IP's to your PC)
