Multiple remote networks without IPSEC

[sandro.bastos]

We are establishing a VPN Site to Site using the IPSEC of PfSense against a LibreSwan Linux, all phase 1 goes up normally, but in phase 2 on only one of them because we have 2 nets in our different cabinet that will communicate with the other side, even making Split of the connection in phase 1 the 2 connect but is connected for a short time and one of them simply falls and does not return again, someone can help me with this case.
