pfsense needs to have two
different interfaces in order to do nat.
you need two interfaces in pfsense and set your modem into bridged
mode and plug it into the interface you set as wan.
That's what
it's set up as just now basically. There's only one ethernet card - a
switch connects that port to both the modem and the rest of the LAN.
I've
configured it before using a normal centos install but when i try to do
it on pfsense it doesn't let me set both the WAN and LAN interfaces to
be the same NIC. It says I must set a WAN interface, and seems LAN is
optional. It says stuff about VLAN but that's beyond my knowledge.
Anyone use a single NIC with pfsense? My
'WAN' interface will just be the ADSL modem which is normally a
virtual/PPP interface which runs over the single ethernet card and the
LAN interface will be ethernet. However it seems to be quite tricky to
get pfsense to accept this.
If not pfsense would something like
smoothwall be a better bet?
