Multiple interfaces setup

I would like to know the correct way to setup multiple interfaces to the
Internet and internal LAN (for SuSE 8.0 prof)
I know what to do, I just do not want that SuSE makes than changes after
I finished ;-)

Interface connections;
eth0 goes to ISP-1 IP address netmask
eth1 goes to ISP-2 single IP address
eth2 goes to ISP-3 single IP address
eth3 goes to the Internal LAN, and

eth0 has also a tunnel for IPv6
eth1 will get as well another tunnel for IPv6
eth3 will have the IPv6-prefix from each ISP, but the remaining address
same for both IPv6 address spaces

I use Monmotha's firewall script with multiple Internet interfaces (new
one, released today)

I want to install zebra for an optimized routing to these 3 ISPs (No
experience yet, but would like to get some hints)
(with private ASN 65001)

At the moment I have setup:
eth0 to the Internet only and use a second router with NAT for the
ISP-2, and with DHCP I have setup that every LAN user uses ISP-2, but
still can use the server local via I have setup the DNS
with internal and external view and apache with both (Internal and
external IP address)

I tried to use Yast Network card configuration and have set the eth1 to the IP address and added a routing for the ISP at eth1, that works from the server, but does not work from the LAN. I have setup the routing gateway in /etc/dhcpd.conf to the IP address or to (alias IP to eth1).

Any hints?
