IPSec with NAT (with two differently sizes subnets)

[amelotti]

Hey folks,

I'm trying to setup an IPSec tunnel but this situation is killing me. The tunnel is UP but without any traffic. I'm thinking if is this because I'm using NAT but with different network size. Infos about this setup:

IPSec IKEv1 Phase 1 (UP)
Phase 2 (UP):
  - local network 192.168.0.0/25
  - network NAT to 192.168.50.0/27

Is this OK? Or I have to do some additional setup?
