Hi,
I am trying to secure my EoIP tunnel with the new feature ipsec secret. Right now, my EoIP is running over a PPTP tunnel which I find very insecure (although it performs really good). My network diagram is exactly the following:

When I am setting up the EoIP tunnel I don’t know what Local Address do I need to set in each end.

If I leave blank the Local Address field, I get this message:
failure: both local and remote addrs must be set for ipsec to work
In Remote Address I suppose that it is the WAN IP of the other end. Am I right?
Can anyone help me set this up?
Thanks in advance.
Best regards
