This is one that I found going through the mailinglist.  I see this asked all the time so thought I'd post it.  (Note - I have not tested this)  Thanks goes to Dayne.


1) First you will need to access the console via ssh.
 
2)Then cp /var/efw/uplinks/main /var/efw/uplinks/link2
 
3)Modify the /var/efw/uplinks/link2/settings file in vi to reflect the other ISP connection. Make sure to change the RTABLE=200 to RTABLE=201.   
 
"This value is used as name of the link specific routing table, as priority within routing rule table (ip rule) and as mark in the iptables mangle table (iptables -t mangle -vnL)" - Peter Endian
 
Some people have reported issues with portforwarding.   
 
"if you use portforwarding, keep in mind that if you have multiple uplinks you have different uplink ip addresses"

LOAD BALANCING WITH 2 OR MORE RED NICS
*************************************

The objective of this small howto is to make a load balance of the internet traffic between 2 or more red nics with STATIC IP (is a must)
1. Configure 1 red nic using the web interface
2. Open a ssh connexion as root to the firewall and enter to the folder /var/efw/uplinks ("cd /var/efw/uplinks")
3. run the command "cp -p -r ./main ./link2 (if you have more red nics repeat this step but with ./link3 ./link4 ./link... you get the point)
4. Enter to each one of the copied folders and edit all of the parameter in the file "settings" except DEFAULT_GATEWAY, leave that one blank
5. Do the previous step with the folder main ( /var/efw/uplinks/main)
6. Recheck that all parameter for all of your links are set OK, and that all DEFAULT_GATEWAY fields are blank (is a must or else it wont balance the traffic)
7. Enter the directory /var/efw/inithooks ("/var/efw/inithooks")
8. add to the files start.local updatered.active.local updatered.inactive.local updatered.local  and updatewizard.local

                          nexthop via <gateway link2> dev <iface link2> weight 1 \
                          nexthop via <gateway link3> dev <iface link3> weight 1 \
                          .
                          .
                          .
  NOTE: remove the " \ " in the last line
  NOTE: i modify ALL those files because i do not know witch one endian use to generate the routing tables.

9. Restart your endian firewall
10. Wait 5 minutes or so an log to the firewall
11. Check your routes with the command "ip route", it shoud show you all the gateways that are using in a round robin balance for the packets that goes out from your network to the internet.
12. HAVE FUN
