I'm using FIBs. The host is in on a private network with gateway of 192.168.1.1 and jails are on public network with their own real/public gateway. FIBs work without the box becoming a gateway: %grep gateway /etc/rc.conf gateway_enable="NO" I have this in system startup to setup "public gateway" for jails: %cat /usr/local/etc/rc.d/0.setfib.sh #!/bin/sh echo setfib 1 for public jails /usr/sbin/setfib 1 /sbin/route add default 216.241.167.1 and in /usr/local/etc/ezjail/myjail I added this line to the end of configs: export jail_myjail_fib="1" [/usr/sbin/jail has FIB support built in, but at that time ezjail did not, so I had to manually add it in the config - nowadays I believe ezjail has FIB support natively, but the resulting config file is the same] The host is using NAT to get out via private IP, and jails are available via public IP. All the IPs are defined in rc.conf the normal _alias way. FIB support as I remember needs a custom kernel - not sure about 9, this is in 8.2. I even run openbsd spamd on the host and using FIBs to start the spamd daemon via a 'setfib 1' wrapper script: %cat /usr/local/etc/rc.d/obspamdfib.sh #!/bin/sh # # this just calls the orignal file, but with setfib 1 /usr/sbin/setfib 1 /usr/local/etc/rc.d.fib/obspamd $1 I had moved the 'obspamd' startup script to rc.d.fib just so a 'setfib 1' wrapper is called. ]Peter[ FIBs are awesome when you don't have many public IPs and when host is _only_ a jail host running no services _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
