Load Balancing Without wiping data

[stupidname]

Hi, 

I ve got 2 fortigate 100d, which are stacked/HA'd. Currently have one ISP all traffic going will go via WAN 1.

I'll be getting a second link put in and wanted to know how to go about putting one ip range on a load balance, 90% WAN2 and 10% WAN1 without re configuring the whole firewall.

Any help would be much appreciated.

You may try  to set up "WAN Link Load Balancing Interface" on v5.2. Thanks.

Check CLI reference from docs.fortinet.com.

Inside the VIP configuration, from

set ldb-method {first-alive | http-host | least-rtt | least-session | round-robin | static | weighted}

you should use "weighted". But I will never use such thing by myself because there are web pages that need a specific outgoing IP-address, either for security reasons or just for a session-keeping, and then such configuration can easily break normal use of web pages if two packets from the same computer come from two or more different external IP-addresses.
