    Hi all,
            I really need some urgent help with this I'm completely confused. I
    have a FreeBSD 4.9 machine running ipfilter ipnat vrrp and a few other
    services, today is the first time I tried to access through the specific
    method but now every interface and every local address I try has the same
    problem. I can ping anything - but any other kind of traffic waits for about
    2 minutes before transmitting - this is true with tcp and udp. I'm trying to
    access machines on the same network - and if I ping -R you can see the same
    effect - pasted below. I've also included the interface that I'm trying to
    do this on although it seems to be happening on all my other interfaces..
    I try to telnet to a cisco router that's on a switch I'm plugged in and I
    see the same behaviour - it just waits then suddenly responds very quickly.
    My IpFilter rules don't log anything until it responds at which time they
    pass it - and tethereal + tcpdump also see if perfectly AFTER the long
    delay.

    It appears that its sitting on the kernel for 2 minutes??? It just does
    NOTHING then all of a sudden responds. The only thing I can find that works
    is icmp - and perfectly. I'm sorry for the urgency but its very high
    priority

    Thanks in advance
    Dave
