Firewall + DNS + NAT + DHCP

G

Currently I have a WRT54GS2 Linksys wireless router and have my FreeBSD server plugged into a wired port on the router.

The FreeBSD server has multiple jails for web servers and a database and some other jails.

Would it be possible to setup a FreeBSD server that is a firewall + dns + nat + dhcp and also set it up as a WAP for my wireless laptop? In addition I still want my jails running on the server.

If the server with the jails is also acting as a router, then would that work?

I have a reverse proxy and that goes to some web servers in different jails. Currently I have an alias to the physical interface, but how would it be if the router was on the same machine?

Example:

ISP ---> cable modem ---> FreeBSD (fw/nat/dns/dhcp/wap) ---> #machine would then have multiple jails on lo1 with private IP's like 10.0.0.100, 10.0.0.101, etc.
