Internal network

A look at the internal network setup of nystrom.nl, maybe it will give some information to others who want to set up anything I use here.
(still a work in progress, more to be added and of course changed as the network changes as well)

The internal network consists of 4 FreeBSD servers running on VIA Mini ITX hardware.
These 4 servers host jails spread out over several LAN/DMZ networks for redundancy.

The jails run;
DNS: DJBDNS, 2 caching and 2 resolving servers pointing to ORSN for the root DNS servers as alternative to the ICANN root servers
Mail: 2 EXIM mail servers
Proxy: 2 Squid servers
Web: 2 Lighttpd servers

Every jail has a backup version in case the original is unavailable for any reason and are created with the ezjail port.

And for storage NFS and Samba are used.
