Load balancing help: keep traffic to one website on WAN it started on?

    I have an RV042 and have just added a connection on WAN2 to setup load balancing. It seems as though it's causing a problem with some sites that require a secure connection (specifically, to one of our online banking sites). The site keeps logging the user off. The bank's tech support said it looks to be tied to load balancing which would make perfect sense since it started at the same time I added the second connection and switched on load balancing.

    When a connection is made to a website/IP, does the router NOT keep the traffic to that site locked on the original WAN it connected to? Is there a way to do that?

    I see a block for protocol binding in the admin. Could I pick HTTPS from the service list, add the accounting departments' IP addresses to the range, then lock them onto WAN1 for ALL outgoing HTTPS stuff (by leaving the destination IPs to all zeros?)?

    Thanks very much!

    Yep, the exact same thing happened to me and thats exactly how i solved it :)

    I JUST did the same thing and it worked as well. It's not only limited to secure sites, it also affects anything with sessions. Most forums have problems with this too. Doesn't this kind of defeat the purpose of load balancing?

    Websurfing has never been that intensive ;) I basically use load balancing for my bittorrenting needs :D

    I set the HTTPS connections to lock to WAN1 eliminating that ONE problem, but if other session-based connections are being dropped, what is the solution? I could swear I read somewhere about a patch/hack that would do this.

    For those of you having this problem, are your dual broadband connections equal in speed?

    I have an RV082 with one broadband connection that is four times faster than the other and have not seen any of this problem. At first I thought it was because of the way the weigthed round robin load balancing allowed another session to be opened. The weighting proportionately biases the opened sessions to the faster WAN at the speed ratio of the WANs and would mostly keep the faster WAN bound to the web site. In effect it became a "loose" protocol binding that could be broken if the extra bandwidth of the second WAN was absolutely needed.

    This was the way WRR worked for firmware 1.3.2, but it doesn't seem to function the same with the latest beta firmware My RV082 still doesn't cause any problems connection to HTTPS sites and I don't think I've read about any others with that problem and this model router.

    If the RV042 works the same way as the RV082 used to work, you might be able to enter your true download speed for WAN1 and a reduced download speed, say one tenth of normal for WAN2 and then release the bound protocol to see if this could help your problem. It might be worth a test.
