Wireless Access

Is there a trick to forcing a GRE tunnel through an IPSec tunnel when the GRE tunnel mode is L2?   My experience with Cisco says I need to use an L3 tunnel for the GRE part.

Thanks!

Hi,

Good morning.

:smileyhappy:

L3 is needed for GRE,because GRE will not survive behind NAT(diffrent routers/gw/fw)
