Hello all,
I have a head office configured with a vigor 2925 router. Our DR site has a vigor 2760 which connects without issue to the head office site.

The vpn has historically been used on windows 2000 servers which run a database (mirrored through the vpn).

New servers are now in situ and the new machines (windows 2012, windows 7 and windows 8) at head office are not able to ping/connect to any machines at the DR site. The old servers are still able to connect without issue.
