I've reset to defaults and setup just the Lan to Lan config. Same crashing/reboot as soon as I "Enable IPSec VPN Service" from the VPN Remote Access Control menu.

But, there is no crash when you reset the router to default settings, ?
Enable all VPN services
and dont setup a VPN profile ?

if yes:
please write here the Lan2Lan profile you use.
anonymize all public IPs or names you use in the profile and all IPSec PSKs or LocalIDs, but dont remove the private IPs.

Maybe then I might be able to help.

I think I've got it working! I found that "Reboot using factory default configuration" was no use. Reloading the .rst version of the firmware seemed to the the only way to provide a completely clean start. When I rebuilt all the settings from scratch I found the IPSEC VPN seems to work. I foolishly then tried to reloading my saved settings and had the problem again. A rebuild from .rst file a second time with manual setup got it working again.

Thanks for your ideas, they helped me find a solution.
