The NIC cards are different on both ends, and I doubt that both systems =
have a bad cable that affects only the default router on both ends, =
although I have checked the cabling and I'm confident that everything's =
OK.

ARP problems are associated most times with a bad NIC card or cable. =
Check that out. I would try not only a new NIC, but a different brand =
and model.

Hi Guys, I'm using two FreeBSD 3.3 systems, each with the latest =
KAME IPsec extensions in order to setup a VPN between two sites. Both =
systems are exhibiting the same problem and I was hoping someone could =
help. During normal operation the VPN works fine, both systems have a =
default route and can reach the Internet via that route. A "netstat -nr" =
shows the route and has an entry for the local router's IP address and =
it's corresponding MAC address. The MAC address is also in the arp table =
and shows up with "arp -a". Unfortunately there appears to be a problem =
that occurs from time to time, about every hour or two, where one of the =
systems loses the ability to reach the Internet. When you login to the =
system you can't telnet to the default router, you get a "Host Down" =
message and an "arp -a" shows that the MAC address is no longer there, =
instead it claims to be "incomplete". Manually adding the entry seems to =
be a work around, but it still makes me nervous. Any ideas? Thanks, =
