Hi all. I have ipsec-tools-0.5-4 in Fedora core 4 machine installed from ipsec-tools-0.5-4.i386.rpm and ipsec-tools-0.5-2.fc3 in Fedora core 3 machine installed from ipsec-tools-0.5-2.fc3.i386.rpm Should I be able to establish IPsec connection between these two machines/versions? If I update ipsec-tools versions to same in both machines, what version should I try? For Fedora there is ipsec-tools-0.6.4-1.1.i386.rpm, does it work only in development version of Fedora? Thank you for any answers! -Teemu Väisänen
