Hi,

I am having some trouble setting up an IPSec VPN between a Vigor 3900 and V3300, the error that I seem to be encountering in the logs is:

Which I believe is an issue with the proposals at each end not matching, as the preshared key for both profiles is the same. Please find posted below links for the proposals on each of the routers. Any help would be greatly appreciated.
