I have 8 static IPs on my pppoe connection. My firewall
is FreeBSD. I can manage to get the net working and NAT'd but I can't
set the default route to one of my static IP. The outgoing address is
always the default router of the PPP (tun0 device) which is not
static. I would like to have the computers behind the NAT to be
visible on the net as one of the static IP.

Clarification of Question by pplevesque-ga on 13 Nov 2006 15:24 PST

I have 8 public IPs on a DSL connection. My provider is using PPPoE
for authentication. To use my IPs on the Internet I bind them on the
physical interface connected to the DSL modem. Those IPs are working
for inbound connection (mail, web, rdp, etc). But I can't get them to
work for outbound connection (tried BitchX -H ip_addr to be sure).
My best practrice would be to make SOURCE NAT on all my outbound
connection the always have the same address on the Internet.

Can you clarify this a bit, do you have 8 different static public IPs,
or do you have 8 different internal IPs in your network? It seems to
me that you are allocated a dynamic public IP by your ISP so I don't
know where the static IP come from.
