Firewall: Filter no port UDP packet!

I have no faith that I will get a satisfactory answer but here goes ..
because of an ongoing, variable irritation, internet dropping problem I have today put the Echolife router tha Talktalk supplied a while back into service again, replacing the original Dlink router they provided ..
not been on long enough to check the drop problem but ....
the log is filled with
Firewall: Filter no port UDP packet!
&
Firewall: Filter no listen TCP packet!

Never seen these in the Dlink log ..
What do they mean, what is the significance and why only on the echolife router?

later ..
going to switch back to Dlink.. download @200k .. upload @ 400 k despite 8120k sync
........

gawd .. shudda left it alone .. almost as bad on the Dlink .. less than 1m down load

Re: Firewall: Filter no port UDP packet!

Windows is an extremely 'chatty' OS and it checks for many things very often, UDP is used for time server synchronisation and updating network information such as that using ICMP. Likewise some processes have to use TCPIP to achieve the same ends, some protocols such as DNS actually use one or both depending on what protocol asked for the info!

Windows doesn't quite follow many of the 'standards' in networking terms. The Huawei is just reporting these 'checks' that it didn't allow to happen from the outside to the windows box that asked for them.

So, wasn't the Dlink doing the same thing .. or just not bothering to report it .. .. I don't recall it being like this last time I tried it .. could it have anything to do with Windows 7 on the wireless laptop, which I didn't have before ..
and why should the whole lot have gone to snail's pace since I tried it .. it has never ever been as slow as this in the past

Sometimes I am tempted to ditch Broadband and go back to dial up

If you are still experiencing drops in sync and have tested with a different modem, filter and ADSL cable at the BT test socket then we can pass to the Network Team to investigate further.

Thanks
