I'm getting the following errors on the concentrator with a connection from an 870 router:
8456 11/04/2006 22:10:34.430 SEV=3 IPSEC/19 RPT=21165 24.167.21.20
IPSEC ESP bad pad length (255) >= buffer length (48)
8457 11/04/2006 22:10:34.430 SEV=3 IPSEC/19 RPT=21166 24.167.21.20
IPSEC ESP bad pad length (107) >= buffer length (56)
Anyone have any ideas what the problem could be?
