Hi,

I need some help. I am running a VPN between a FreeBSD 4.3 box and another FreeBSD 4.7 box.
I am using the IPSEC / Racoon setup that comes with FreeBSD. I have not compiled anything:
I inherited sysadmin duties for these boxen from another fellow. They had been working
just fine when I first "acquired" them. Since that time, my customer has had two moves when
they physically consolidated their two offices into one new office. At that time, the VPN
was torn down, as there was only one box.

Now they have opened a new "branch" office (actually a "home" office) and have tasked me
with re-establishing the VPN to this separate location. I took the second box and re-located
it. The only changes made were to the /etc/hosts (new host name(s) and IP addresses),
/etc/resolv.conf (new dns servers), and some tweaks to /etc/rc.conf, and IP re-configurations
in the /usr/local/etc/rc.d/ipsec.sh startup script.

The IPSEC VPN has been up and down, but frustratingly mostly down since this latest "move".
However, the VPN *was* working, and working well just two days ago. Today I checked, and it
is again down, and the "primary" company server is logging lots and lots of these messages:
