[Efw-user] Understanding Endian Load Balancing Feature

Hi, I intend to try and install Endian Firewall 2.2 but I need help
understanding the load balancing feature as there is really not much info
about it (or I probably just don't understand what I am reading in the
documentation :P ).

Anyway, assuming that I have 2 webservers, both running the same sites, with
different internal IP addresses (kind of a redundant setup), can the Endian
Firewall load balance the external traffic going to the webservers?

Webserver 1 : Listening on IP 10.1.1.2 port 80
Webserver 2 : Listening on IP 10.1.1.3 port 80

Basically, what I am asking is whether using Endian Firewall 2.2 load
balancing feature eliminate me from having 2 separate dedicated
high-availability load-balancers (Heartbeat/HAProxy) behind the firewall.

Thanks and hope someone can enlighten me.

By my understanding of the text the load balancing is for balancing lan
connectivity to the internet ie u have 2 adsl lines and want to spread
the load of interested access across the two lines. to load balance
between to http servers or any other for that matter would require dns
load balancing or one incoming line connecting to a load balancing
server in front of the servers. I'm open to correction but thats the
short story ..

Unless this has changed very, very recently (and I would love to hear it), there is no outbound load balancing for multiple RED uplinks. There is automated failover, but no load balancing.

It's a feature request I have been begging for, and would really round-out the uplink features substantially.

as far I know the new 2.2 version includes load balancing. When i tested
it I could see in vmware traffic going through all interfaces and the
graphs reflected traffic going through all int's as well.

It's listed as an explicit feature of the appliances and the production software, but not in the community edition. I would love to hear differently, but last time I asked, I got a reply from one of the developers and they said it was NOT there.
Will this release support multiple WAN/RED interfaces -- with each using
DHCP -- for load balancing and/or failover???
Yes, multiple uplinks are possible, in failover mode and/or up at the
same time. Load balancing is not possible due to a problem with the
current kernel.

I honestly don't know if/when they will "fix it". Really it's a "Feature Request", not a bug.

The developers must be very busy, as Peter (amongst others, I think) is typically pretty responsive and participates in the mailing-list. He would probably be able to give you the best response as to where it is, and when we should fully expect it.

Best of luck.

I think you are correct. Outgoing connections will load balance, it
seems. incoming connections will load balance with some kind of dns load
balancing or and internal system like heartbeat. How would dyndns work
with multiple connections though? Which interface ip will it use to
update dyndns with?

May I ask where is the docs for the new 2.2 version. The online docs
seems to be still for the old one. I've been playing around with the
beta version and especially with the failover feature. Pretty much the
main reason I would use endian. I have a vmware vm built with the
following network setup:

Green: Connected to a NAT vmnet and allows my host machine to talk to
the firewall
Red1: Connected to a Bridged vmnet and allows my firewall to talk to the
net via the local lan's dhcp
Red2: Connected to a Bridged vmnet and allows my firewall to talk to the
net via the local lan's dhcp as a second link
Red3: Connected to a Bridged vmnet and allows my firewall to talk to the

I am experiencing similar but not exact problem with 2.2.rc2:

NO VMWare...

P4 2.0Ghz, 1GB Ram, 80GB IDE
5 Nics

Green/Orange/Blue/Red(Main Uplink)/Red(2nd Uplink)
192.168.2.1/192.168.3.1/192.168.4.1/192.168.1.139/10.28.210.251

With Main Uplink and 2nd Uplink in Managed mode, unplugging Main Uplink
causes 25 second delay (25 second packet loss) before failover routes
traffic over 2nd Uplink.

With Main Uplink and 2nd Uplink Managed unchecked, I can uncheck active next
to Main Uplink and there is no packet loss as traffic routes over 2nd Uplink
immediately. Manual ticking Active next to either link is instantaneous.

What is causing delay when in managed mode? Is this a bug or a setting
issue? How to resolve?

May I ask where is the docs for the new 2.2 version. The online docs
seems to be still for the old one. I've been playing around with the
beta version and especially with the failover feature. Pretty much the
main reason I would use endian. I have a vmware vm built with the
Green: Connected to a NAT vmnet and allows my host machine to talk to
the firewall
Red1: Connected to a Bridged vmnet and allows my firewall to talk to the
net via the local lan's dhcp
Red2: Connected to a Bridged vmnet and allows my firewall to talk to the
net via the local lan's dhcp as a second link
Red3: Connected to a Bridged vmnet and allows my firewall to talk to the
net via the local lan's dhcp as a third link
