UDP traffic - to block or not to block

    I connected to broadband on Friday 18 March via a wireless network (Linksys WAG54G & WUSB54. At one level it's all working OK. My internet access works fine and no major functions seem to be missing/not working.

    I use a Sygate firewall on the my PC and when I look at the traffic log there seems to be a lot of UDP traffic blocked from the modem. I know very little about this so do not know what is legitimate and what is not. The WAG54G is set to limt the network for the moment to my PC only.

    I suspect that what is being suppressed is valid internal network traffic but am not sure. The modem appears to be cycling around its available ports to find access. It is trying to use my local port 162

    I would be grateful for any advice. The basic question is whether this is legitimate and what I need to achieve in terms of a rule from the Sygate firewall to allow legitimate operation of the wireless network. (I would add the log as an attachment but am not sure how to do so.
