Firewall causing problems downloading?

Archived from groups: comp.security.firewalls (More info?)

I've noticed recently that anytime I try to download a file of any size
(> 2MB), I tend to lose my internet connectivity. I can *always* solve
this problem by unplugging my cable modem and letting it sit for a few
seconds before plugging it back in.

I'm also using Windows XP firewall, and recently started logging to the
pfirewall.log file just to see if it might be a firewall-related issue.

Here is an excerpt from that file:

2005-08-20 07:51:02 DROP UDP 192.168.1.1 192.168.1.255 6386 162 122 - -
- - - - - RECEIVE
2005-08-20 07:51:07 DROP UDP 192.168.1.1 192.168.1.255 6387 162 122 - -
- - - - - RECEIVE
2005-08-20 07:51:12 DROP UDP 192.168.1.1 192.168.1.255 6388 162 122 - -
- - - - - RECEIVE
2005-08-20 07:51:12 DROP UDP 192.168.1.1 192.168.1.255 6389 162 145 - -
- - - - - RECEIVE
2005-08-20 07:51:14 DROP UDP 192.168.1.1 192.168.1.255 6390 162 143 - -
- - - - - RECEIVE


The only thing that concerns me is the seemingly sequential ports that
are being dropped - 6386, 6387, 6388, etc...

Could all of this somehow be related to my problem downloading?

    Since it is only traffic within your own system, you might as well unblock
    it and find out.

    udp 162 is snmp traps, so 192.168.1.1 is broadcasting (dest of
    192.168.1.255). Is the source your home router?
