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
net via the local lan's dhcp as a third link
From I tests it looks like bandwidth load balancing is working ok. How
does it do the load balancing exactly? per tcp connection?
How does the failover work, or is it still in progress as it does not
seem to be working well. When I disconnect one of the virtual nic's in
vmware the firewall does not detect that the link is down. In fact you
have to manually tick "manage" and then untick "active". I can then
again tick manage and the link will detect that it is down and keep
attempting to reconnect until I re-enable the vmnic. When the main link
is down the 2nd link will then take the load and pings will continue,
but when i manually disconnect the 2nd link, leaving 3rd link the only
active one failover will not happen. I have to then manually disconnect
the 3rd link and reconnect it and pings will continue.
Should all of this not be automatic or am I missing something? While
playing with the links in non-managed mode failover is seamless. I can
drop link 1, no packet loss, drop 2, no packet loss, drop 3, no
connection as expected, reconnect 1 or 2 or 3 and connection back again.
I'm even when I change the red nics to static and disable the nic in
vmware it still does not detect that it has gone down. how does endian
actually detect a down link? I tried doing ifconfig eth1 down and it
still does not detect that it's gone down.
Thanks

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 <http://10.1.1.2/> port 80
Webserver 2 : Listening on IP 10.1.1.3 <http://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 ..
