I am having trouble to get my VPN working.

When troubleshooting I came across this note:

6. Was the same subnet mask used in configuring all VPN nodes?

The answer is Yes and No. The public interface uses a different mask,
but
the adresses of the VPN use the same.

master = 255.255.255.252
slave1=255.255.255.252
slave 2=255.255.255.248

Will this not work ?

Thanks for helping,

Regards,

Paul
