Hi talatt,
-
Is-there any proven VPN GRE Tunnel configuration that works between Cisco 867VAE VPN Router and RV50 Modem ?
A: For the Cisco 867VAE specifically? No. But I don’t see why it shouldn’t work considering GRE is a Cisco tunneling protocol which ALEOS supports. -
If it is not possible which type of VPN router or Concentrator shall I use ?
A: Sierra doesn’t recommend any particular brand. I would just stick to the Cisco867VAE instead.
Regards,
Nick
