Hi All

I'm trying to set up a Lan to Lan VPN between a Vigor 2925 and a WatchGuard Firebox x750. It's been a while since I've done one of these (over 6 years...) and I'm having a few issues getting this working. Currently the VPN is showing as connected for about 8 seconds. It then drops and tries to reconnect. I'm sure I've made a config error somewhere but I'm struggling to track it down. Below is a copy of the Syslog from the Vigor (IP and names removed). I was hoping someone could take a quick look and let me know what the log errors mean, the duplicate packet one is one I can't remember seeing before. Any help is much appreciated.

Thanks

Chris
