    Hi everyone.
    I thought the firewall on my router was supposed to protect me from inbound events recorded by the firewall on my pc. I installed a Motorola WR850GP wireless router a little over a week ago. My XP desktop is wired to the router and my W98se laptop is connected wireless. I left the 3rd party firewalls on just to see if there would be any inbound events. There wasn't for a while. But the last 3 or 4 days there has been on the Xp machine. 2 today, which is far less than before i installed the router. I thought there was a Motorola forum but haven't found it. I have all the recomended encryption and made passwords on the router. Does anyone know if there is a way to stop this? I was under the impression that you should turn off 3rd party firewalls when using a router firewall. Now I'm afraid to. I was looking in to changing IP addresses on the computers in the routers settings but I don't know if this is the problem. I know DHCP is enabled if this helps. Don't know if I should change those settings to be more secure. The firewall on the desktop is McAfee and on the laptop, Zone Alarm. So far no access attempts have been recorded on the laptop. Thanks.

    Without explaining the events we can't tell you what is occuring and even if its an inbound "threat". Inbound attempts can come in on a router for a number of reasons. The big question is it a threat?

    Something as innocuous as your Anti-virus trying to run an update will generate an inbound connection...

    NAT firewalls do not STOP all incoming connections they actually filter incoming connections. Certain things like port 80 and things like that are open specifically for web browsing.

    DHCP enabled or disabled does nothing to provide security.

    As well check and make sure something is not in the DMZ.... DMZ places your PC totally outside the NAT firewall.

    No firewall will protect you from everything! Just because you behind a router & a software firewall your not virus free, if someone's surfing Porn & warez etc websites, I don't care what firewall your behind, you will catch something. It all comes down to where you go & emails as well.

    Thanks for your replies. I went to the link that was posted. I'll go back and read more. I don't recall ever seeing that site. I can't see any problems with my router configuration. I guess it doesn't hurt to keep the firewalls on as an extra layer of protection, as far as I know. Thanks again.
