how to stealth pings with BEFSR41v4

    Tried registering but still not receiving a confirmation email so I'll just post here in the open forum.

    I just purchased and installed a BEFSR41 v4 router and upgraded the firmware accordingly. I previously has a Wireless-B BEFW11S4 which was fine until it died - I have no need for wireless so I got the BEFSR41 to replace it. My issue is that when I run Symantec's security scan, everything is stealth BUT one thing:

    "ICMP Ping - status - OPEN
    Ping is a network troubleshooting utility. It asks your computer to acknowledge its existence. If your computer responds positively to a ping, hackers are more likely to target your computer."

    With the old router, everything came back as stealth.

    I'm running a home network with XP Pro and W2000pro on the other PC.

    Since installing this new router, I'm getting hammered by pings at least once every 10 minutes, non-stop 24hours a day. I use ZoneAlarm's free firewall which is alerting me to the pings (and blocking them) every time they come, which in itself is a nuisance because of the popup alert windows appearing on top of whatever I'm doing. I could stop the alerts of course, but I'd rather stealth the ICMP ping, as it was with the old router.

    The pings seem to be coming in on my UDP port 1027.

    I have made no changes other than the change of router, so presumably the router is responsible for the open status for ICMP pings.

    Can someone please advise me how to stealth this so it cannot be seen? If you need to know any current settings on my router setup, just ask.

    Please help - these friggin ping messages are driving me NUTS!

    Thanks Linksys for not helping - I'll be returning the router this weekend, and be aware an associate will be cancelling their business contract with you as a result, which is certainly worth a lot more than my insignificant custom.

    You do realize that this is not an official Linksys forum? In fact, aside from being about Linksys products, I believe this site has no association whatsoever with Linksys.

    By the way, the reason I haven't responded to your posts (up to now) is because I don't have a BEFSR41 v4 router. The BEFSR41 v1 router that I have blocks ping's just fine, thank you.

    While I'm at it, what do you mean by "The pings seem to be coming in on my UDP port 1027"? A ping is an ICMP echo request, and as such, has no associated port number. The port number is an artifact of the TCP or UDP protocol.

    ok thanks Ron, just very frustrating with the alert interuptions. I have contacted linksys support via email seeking a resolution - sorry, thought this forum was their official support forum.
