Load balancing using adsl

[deucn]

Hello,

I have seen interesting documents on Load Balancing using ADSL in this web site. I have a small doubt. Say there are two ADSL connectivity both with dynamic IP. I need to host a server that should be kept online always. My question is as follows

How can i configure a load balancer (say D-Link or TL-R480T) so that the web server in DMZ could be contacted when the Load balancing is enabled. For eg., say the WAN1 is having a.b.c.d IP, WAN2 is having w.x.y.z IP. Now how can i access the server kept in DMZ? There are two routes to the destination.

if i give say http://a.b.c.d i will get the web site of the DMZ server if the WAN1 link is up, if it is down, then i will not get that.

If i give http://w.x.y.z, i will get the website of the DMZ server if the WAN2 link is up, if it is down, then i will not get that.

Now how can i make sure that this problem will not creep up. Is there any function in the load balancing router to take care such a problem? Or is there any web service like DDNS that can help me fix this problem.

Thank You in advance.

warm regards

1. enable port forward in both adsl modems to your web server
2. enable dyndns registration on both adsl modems, assume they are airtel.dyndns.org and bsnl.dyndns.org
3. register a domain and configure dns such that www.domain.com is a CNAME of both airtel.dyndns.org and bsnl.dyndns.org
4. and use www.domain.com in the browser, the browser will take of load balancing between airtel and bsnl , it will connect to the IP which is alive

Thanks a lot for the quick response. Will it make a problem if the connection is https? will the browser take care of the session tracking? Take care,Warm regards.

yes.. session tracking will work, as the requests is handled by same web server, even when IP changes.and this works with https too
