Site to Site VPN not coming back up

[Anonymous]

We’ve been using Apple’s site-to-site VPN over our Xserve G5s and
DSL-connected WAN for the last 6 months. Often when one end of the VPN
goes offline (could be a power outage, DSL failure, etc) and comes back up the VPN does
not reconnect. To get it to reconnect we need to restart the VPN
service at either end. Early this morning we had a power outage and the
VPN did not reconnect; our remote office was unable to work without our
intervention.

What could be causing this? Further, is there a log file for s2s connections
(because nothing comes up in vpn.log)?

We’re running 10.4.6 on both Xserves, and each has a public IP.

Well, I have been trying to get mine to establish in the first place, and never have, I would be interested to know how you got it setup in the first place, so Maybe I could help troubleshoot it with you.

In my settings I have
S1: AAA.AAA.AAA.AAA
S2: ZZZ.ZZZ.ZZZ.ZZZ

Local Adresses
S1:192.168.1.0
S2:192.168.2.0
Both Setup in s2sVPNAdmin with CIDR /24

I have them both setup using the same shared secret setup in the VPN pane of the server admin tool. I have them using the same Firewall settings allowed for in the Linking two or more networks info on the Network Services Admin PDF on the Apple Site. (Pgs 112-116)

Unfortunately when I turn VPN on After it tells me to, no link is established.
So anyone with answers, Please assist.
