Urgent 4.9 networking problems

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
