HI,

I have cisco router RV016 with two wan configured and working fine. My problem is because some sites like Banks block the access when the connection change the IP WAN1 to IP WAN2. How I can configure the router to use any wan, but stay  on that wan, without change until another connection ?

Thanks

Need some clarification.  From your original note, you have two WAN connections.  Are trying to use these in a load-balancing configuration or are you trying to use them for failover?  When you say that you want to use any WAN but stay on that WAN until a difference connection, I'm not understanding what you are trying to do?

I´m using as load balancing.  
For example, explaining better : WAN1 ip 200.200.200.300 and WAN2 ip 200.200.200.400. So, if i´m using my bank online the IP must be the same while i´m using it. If the connection starts with ip of WAN1 and in the midle of the access changes to ip of WAN2 the connection was blocked by the bank.

Okay, any internal routing protocol or just using default/static routing?

Jose, could you post the configs of both the WAN interfaces please?

Okay, I am working of the following assumptions:

1.  Interface WAN 1 is your desired primary interface and WAN 2 is your desired secondary
3.  You are using static default routes to egress from the WAN router to the Internet
2.  Your priority is for connection stability over load balancing and that being the case, as long as you maintain failover, then load balancing is nice but not completely necessary

That all noted, change your default static routes to look like this:

ip route 0.0.0.0 0.0.0.0 186.228.xxx.yyz (where 186.228.xxx.yyz is the provider edge IP)
ip route 0.0.0.0 0.0.0.0 200.152.xxx.yyz 10 (where 200.152.xxx.yyz is the provider edge IP)

Open in new window


Note*  in the second line of code, be sure to include the 10 after the PE IP.  This metric pushes preference to the default route in the first line.  This is called a floating static or floating default route.  What this will do is send all traffic out the default route in line 1 unless that interface goes down.  In that event, the traffic will swing to the route in line 2.
