There is ng_mppc(4) netgraph node capable to perform relatively weak MPPE encryption (and/or compression) but it is designed to work with ng_ppp(4) node encapsulating IP packets into PPP frames. I doubt it's very efficient for inter-jail traffic. Why do you need encryption for inter-jails traffic in first place? Encryption is needed for traffic passing untrusted channels where data interception is possible but inter-jail traffic does not leave the kernel at all until it hits destination jail. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
