Sites blocked - access denied error

Post by benjik » Mon Oct 08, 2018 9:08 pm

Hi,

I am on the NBN 50 plan and have recently switched to Exetel. For the past month I have been unable to access the following sites:

www.woolworths.com.au
www.opsm.com.au
www.bigw.com.au
www.bom.gov.au

I get the error "Access denied. You dont have permission to access <sitename> on this server.
I have tried resetting the IP address several times and this works for 24 hours but after that I get the same error. I have ran multiple virus scans on all computers and connected devices. Some viruses were found some weeks ago before I reset the IP address but there are none found now.
A google search revealed the IP address may have may been blacklisted due to viruses but I tried checking this and the address seems okay.
I have been in contact with Exetel support who suggested I contact the webmasters of these sites to found out what is going on.
Is there anything else I could check such as router settings? I have tried changing the DNS settings in the router to use the google settings without luck.

Thanks.

Since you have tested with multiple WAN IP address changes, I strongly suggest you to webmasters of these sites to found out what is going on, as this seems to be blocking the WAN IP for a specific reason. Otherwise it cannot work for sometime after having the IP address change. They should provide you a report for getting the IP blacklisted in their sites and based on that you can work accordingly to a permanent solution.

It's unlikely that woolworths.com.au are blocking his IP...

I'd suggest there's a proxy being used or similar circumstance and that's where he is getting the access denied message.. Simply put though - it's the user's PC.

There is no proxy, vpn or virus on any device/pc but I'm unable to access these sites.
I haven't had any response from the webmasters of these sites either.
I'll change the IP adddress again yet again and if it still doesn't help I'll be forced to change ISP's.

I have further checked on this, since there is no response for you from the site admins. We did a port check using www.woolworths.com.au and the port is opened from the Exetel network.

If the issue persists, you may also check with following for the testing purposes only.

1. Lower the MTU value in the modem to 1300 and check the sites.
2. Telnet the site to the port 80.
Example - telnet www.woolworths.com.au 80
Once you have done that, please check whether you get a message in the screen or whether the screen goes blank.

Yes all the sites are working again because I have changed the IP address. I will wait and see if I can still access the sites in a few days and try your suggestions if the problem returns. Thanks.

Thank you. Sites are working after changing the IP means, definitely there is something you need to check with the site admins, as changing the ISP won't fix this problem.
