Solution on Link Failover for Hosted Webserver

Hi,

One of my customer has Web based application which is hosted over internet on IP provided by ISP. Challange is in case, the ISP link fails webserver is not available. Customer is planning to add one more link from different ISP. How do I Load balance both this links and have webserver being accessible from any of the link in case of link failover.

Re: Solution on Link Failover for Hosted Webserver

Assuming that we have a webserver hosted by us on our internal network as 192.168.1.1 and we map it to pix outside interface ip address x.x.x.x as follows:

static (inside,outside) x.x.x.x 192.168.1.1 netmask 255.255.255.255 then any traffic from outside world hitting to x.x.x.x will directly be routed to 192.168.1.1. Hence, we use port forwarding as follows:static (inside,outside) tcp interface 80 192.168.1.1 80 so that only the port 80 traffic destined to x.x.x.x should be forwarded to 192.168.1.1 and not all the traffic. And you can also do by change the ISP cable to your device and reconfigure it .
