anyone else had this problem, upgraded from 2.5.7.1 this morning to 2.6, was delighted with all the new toys under voip menu etc, but then noticed not a single one of my vpns was working. checked the ipsec policy table and all my ip setups are all there and connected fine to the net, but ipsec vpns would not connect. Rolled it back to 2.5.7.1 and all the vpns fired up damm near instantly.

I'd try clearing out and re-entering the VPN profiles, I've seen similar stuff happen when going from 2.5.7 to 2.6, deleting and re-entering the VPN details fixed it straight away.

You can fix it by choosing Main Mode / Agressive mode on the advanced options...
