Hi, I need to configure a GRE over IPsec tunnel between a RUT240 and a Cisco 2800 Router. I configured the GRE tunnel and it worked great. When I tried to secure it with IPSec it doesn't work. I checked the phase 1 and 2 parameters and it is matching, but the IPsec doesn't pass the phase 1.
Does anyone know if the RUT240 supports GRE over IPsec? If so, it works with Cisco routers?
I would appreciate if someone could help me with this configuration issue.
