Hi, I have the following questions about ipsec tunnels on alix/pfsense2.0 1. Upon power cycle does SAD and SPD are erased? or are persistent? 2. My wan is a 3g modem, if i change it with other modem/same model with other external ip. do i need to erase something like SAD or SPD? or they are erased automatically from previous connection 3g modem? Thank you.
