Dear Aaron, as Chris replied you, the solution is to use DNAT with L4xNAT profile, more information in the official documentation:
Have a look here and check DNAT section: https://www.zenloadbalancer.com/knowledge-base/enterprise-edition-v3-04-administration-guide/enterprise-edition-v3-04-l4xnat-profile-farms/ Once you apply this your backends will use the Load Balancer as gateway, it means that the backend ips will be known out of the backend network, so you have to apply once of those sections: 1.- Make new route rules in your network for the backend network in order to be routed along the other networks. 2.- Create a special NAT rule in the load balancer. There is a special file where to setup special routes and rules: - Edit the file */usr/local/zenloadbalancer/config/zlb-start* and include the rule: /sbin/iptables -t nat -A POSTROUTING -s <backends_subnet> -d <destination_subnet> -o <output_if> -j MASQUERADE Where: -s <backends_subnet> is the source ip subnet in the form 192.168.0.0/24, where the backends are located. -d <destination_subnet> is the destination address and it's an optional parameter. -o <output_if> is the output interface where to perform the masquerade, (ex: eth0) I hope it helps you 2016-09-22 23:01 GMT+02:00 Aaron Echols <aech...@bfcsmail.com>: > They are pointing directly to the default gateway for that network.
