I have an SRX5308 with two WANs (a 100Mb WAN1 fuse and an adsl 5Mb WAN2 backup) I need both links to be up all the time (as in load balancing mode) because there are open ports on the Two links, but I want the majority of com lan to wan go through fiber (WAN1)? How can I do ? if i config load balancing, link's are UP but sometime internet trafic goes thru ADSL (WWAN2) if i config rollover ADSL (wan2) is DOWN Thank's

Hi Golgotha, Were you able to test using LB and firewall rules? Let us know if you need more help. Thanks,

Hello Golgotha,

Welcome to the community!

It is normal for the router to use the WAN2 (when in LB mode). When using weighted load balancing, balance weights are calculated based on WAN link speed and available WAN bandwidth. There is also the round-robin option, see definition below:

With round-robin load balancing, new traffic connections are sent over a WAN link in a serial method irrespective of bandwidth or link speed. For example, if the WAN1, WAN2, and WAN3 interfaces are active in a round-robin load balancing mode, an HTTP request could first be sent over the WAN1 interface, then a new FTP session could start on the WAN2 interface, and then any new connection to the Internet could be made on the WAN3 interface. This load balancing method ensures that a single WAN interface does not carry a disproportionate distribution of sessions.

See more information here (page 42).

Thanks,

  Thank you for this quick response, i understand the operation. On the other hand the use I wanted to make was a little different. The WAN1 must be used for all outgoing calls and some incoming calls. WAN2 should only be used for incoming calls on certain ports (VOIP). If I configure in WAN1 alone, then WAN2 is always "down" if I configure in LB then the outgoing traffic is distributed on both WAN
