Hi Simon, > Strongswan (well, I'm pretty sure it's Strongswan) adds a /32 IP to my > loopback interface when bringing up the connection.
I don't think it is. strongSwan only adds virtual IPs (assigned from the other peer, and since you don't request one with leftsourceip, there won't be any) to local interfaces, and to `lo` only if explicitly configured to do so (via charon.install_virtual_ip_on). There will also be a log message if an IP address is installed. Regards, Tobias
