Question: Updating single dynamic IP address using two seperate ISP's. I have a small scenario that I would like to get some comments on. I was running a business website from my house on a server, though my ISP assigned a dynamic IP address to my server. I was running winIP (dynamic IP update) and using thatip.com services. Recently I switched my ISP to fiber connection (Very fast). The issue now is that my new ISP blocks all incoming http traffic on port 80, and I am not able to access my websites. My previous ISP did not block any incoming http traffic on port 80. I have not disconnected my previous ISP yet, basically thinking of what to do. So at the moment I have service from two different ISP’s. I guess one of the way to accomplish this when using the new ISP (blocks port 80) is to run the web server at any other ports e.g. 8080 and use a any service on the internet to re-direct any traffic coming on port 80 to port 8080. Other solution may include upgrading my account with new ISP so that port 80 is not blocked (it’s quite expensive), or hosting the website at a remote site (that would require extensive amount of time and some database re-creations). What if I use both ISP’s (two network cards in the same server). Since my domain resolves to whatever the winIP updates, is there a way that I can make winIP update the previous ISP dynamic IP but not the new ISP dynamic assigned IP. This way anybody would be able access http service (coming in through my previous ISP) and any browsing or outgoing traffic on port 80 will have…I guess more bandwidth…., or does this makes since at all. Any comments or solution would be nice. Regards

If you look at the ipconfig command, it seems possible to release and renew just one of the adapters. No matter what, you are going to be paying for 2 ISPs. It may be cheaper to pay a web hosting service to host your site and cancel the first ISP. You have been lucky that they haven't seen the traffic in the first place. Who knows how much longer that will last?

Redirecting port 80 to port 8080 as you describe wont work. If you ISP is blocking port 80 you just wont see any traffic to re-direct. The only way it could be made to work is to instruct anyone that wants to use you web site to indicate port 8080 in the URL. Like so: www.yoururl.com:8080 Port 80 being the default HTTP port. Personally I would get a different ISP. An ISP that is blocking port 80 is short of bandwidth and doesn't want its customers hosting their own web sites taking or more bandwidth than average. Stuart
