ASA 5505 Losing connections

Hi Guys,

My connection to the internet keeps dropping - as soon as it does if I ping the other computers on the network and click on the asdm reconnect icon it reconnects fine, if I do not ping the other computers it will not reconnect - any ideas?

I also get the following messgae just before losing connection:

3 Jul 09 2010 08:55:02 710003 192.168.1.11 50366 192.168.1.1 80 TCP access denied by ACL from 192.168.1.11/50366 to inside:192.168.1.1/80

Can anyone explain what this is?

My config file has these entries:
http server enable
http 192.168.1.0 255.255.255.0 inside

should I change it to 192.168.1.1 ?

Could you post the full config of your ASA? Could you also briefly explain how your ASA is connected. What's on the inside and outside of the ASA?
