Thanks for your advice and apologies for not replying sooner.

I've added a new rule as detailed above but I am still seeing the firewall icon.

I've checked within Comodo and LW has an unlimited application control rule as well as the network control rule.

Looking at the connections monitor, there is plenty of traffic (through a number of different ports, not just the LW listening port).

As searches, downloads & uploads seem unaffected I don't understand what is being blocked by Comodo.

Any further suggestions or an explanation gratefully received.

Thanks in advance.

Ummm...I don't know. I've never had any trouble with mine, once a rule was created.
In LW go tools > options > bug reports > view example. Scroll down to 'recieved incoming this session'...is it true or false?

Are you using Win XP? Go to control panel > windows firewall & check that the XP firewall is off.

Since your uploads aren't effected, it doesn't sound like a big drama. Does the firewall indicator show all the time, or does it come & go?

Also double check your port forwarding setup & make sure nothing's changed there.

Thanks for persevering Birdy.

In following your checklist I discovered something odd which may be relevant.

I'll get it checked out and let you know.

Regards.
