Blocking traffic on Port 80 except for Google Earth
« on: March 29, 2012, 06:48:27 AM »

Hi!

I've blocked all traffic on port 80 (Advanced-Access Control- Apply Advanced Port Filter- All IP range and Port 80 selected) to avoid any kind of Web Access. I won't use Web Filter because there are too many URLs to be blocked.

However I have a problem to keep Google Earth working, since it uses port 80.

Is there a way to keep Google Earth working, even blocking traffic on Port 80? I've tried configuring an application rule to let Google Earth working, but it didn't work (it seems that I can not create an exception for Filter Port) .

I appreciate any suggestion  ;)

Daniel

You've blocked all Internet access thus you've blocked GE. Theres no way to only unblock it and keep the rest out. Port 80 and 88 are main Internet ports for most everything. You block those you block everything.

There is no work around for that if your blocking those ports.

Thanks for your help FurryNutz!

However, do you know a way to block Internet Access without blocking port 80?

As I said before, Web Filter is not a choice, since I want to block all Web Access.

I would set up a schedule and use Access control if your trying to block web access. Are you trying to block web access ALL the time or just certain time frames? Are you trying to block access for certain devices or PCs?

Your probably asking on blocking something vs what routers are designed to do. Yes they can block certain things and allow certain thing depending on there features however what your asking is probably beyond the scope of what these routers are designed to do. Three mainly set to allow everything, then customizing some things to block.

Hi Furry!

I have to block Internet Access for a few PCs for specific periods: 08:00-12:00 and 14:00-18:00.

In Access Control I created a policy with a scheduling. The problem is how can I block Internet Access keeping Applications that uses Port 80 running. Applications Rules doesn't create exception for Port Fitering.

I have tried to let a IP Range for Google Earth, but it didn't work because Google Earth IP changes every day  :'(

I think your not going to be able to have the router do what your asking. I believe it would probably take a different product to do this. Probably something like a firewall device like DLinks NetDefend firewall devices maybe working in concert with this router. I might call DLink sales and ask them about this and tell them what your trying to do. Maybe they can recommend a course of action for you.

Let us know how it goes.

Hi FurryNuts!

I'll have to look for a better solution, i.e Sonicwall NSA250M, since DIR-655 does not offer flexibility to setup a better access control.

Anyway, thanks for your help!

Well these routers are just that, routers and offer some good features that work well for the average home user. They are designed with the idea of getting people online and connected with out much hassle. Any extra needs that users come up with or need that goes beyond the scope of what these routers were designed for is something that users have to understand, that some of these routers just don't support. These routers have great features for what they are intended to be. These routers are fairly flexible and it comes down to what users needs are vs what these routers can offer to support that. Users sometimes over expect routers to offer any flexibility in users needs or expect them to have feature like other router Mfrs. In most cases they can, however in some cases, they just aren't designed too.

Good luck.
