oops, i got so distracted by part c to your email, that I read right
over your load-balancing requirements. unless it got included in
dublin, ECMP (Equal-cost multi-path) routing is not available in
vyatta at this time. you can do the failover though, you just add a
second default route with a higher metric, ie:
core1# set protocols static route 0.0.0.0/0 qualified-next-hop
1.2.3.4 metric 10

a and b are simple, almost any router including vyatta can do this.
for c, are you saying you want any user with any random ip
configuration on their machine to be able to plug in and get online
with that random ip, subnet, and gateway? That's a heck of a
request and I'm not sure how it would be possible for vyatta (or
any other router) to know what the user is using, assign itself the
correct ip address that the user is trying to use as a gateway and
create an outbound NAT. I suppose you might could cobble something
together with tshark by looking at arp requests and some
intelligent guessing maybe... but seriously... how hard is it to
click "obtain settings from DHCP"?
I've used mikrotik pretty extensively, and I don't recall ever
seeing an option like this. I must be misunderstanding your
request, perhaps you could explain a little better? If you know
what the settings are on the computers that come in without dhcp
enabled, you could set up a secondary ip on the eth2 interface and
create a matchinf outbound nat rule, that would be easy. but if its
completely random and you dont know what it is ahead of time....

Hello List,
My goal is:
================================================================
1) a box with 3 ethernet cards (interfaces): eth0, eth1, eth2;
2) eth0 attached to internet access provider ISP0;
eth1 attached to internet access provider ISP1;
eth2 attached to local dynamic LAN users;
================================================================
What I need or wish:
a) the router be able to use these 2 WAN links, load balancing and
in case of failure of one link... switch all the requests to the
second available link; and when the failure link comes back on...
do the load balancing again;
b) have dhcp server binded to eth2 as above for users with dhcp
client enabled;
c) now for those who use static IP configurations, I mean: with
static IP, static gateway and DNS servers:
==> and these static configurations does not belong to our eth2
lan subnet.
TODAY I have to go to this user laptop and change manually its IP
configuration... changing them to dynamic IP setup to receive our
dhcp IP configuration. This is what I do not want anymore.
==> I wish that VYATTA be able to route... to allow this user with
any static IP configuration to access internet... i.e. to be
routed to internet and browse the internet as other regular dhcp
users.
Is ir possible with VYATTA?
I saw a solution that provides this "amazing and nice" feature
called MIKROTIK/MAXINA...
Thanks in advance,
mson77
