Setting DNS to block porn site using Sagemcom FAST5366TN-A

I NEED to change the DNS Servers on my new NBN Modem ( Sagemcom FAST5366TN-A) to link back to OpenDNS to limit porn and adult sites on my kids computers and devices.   Is there another option that is provided by Optus to meet this need - if so let me know.

Seems the new modem is locked down thus creating an  situation where my provider (Optus) is opening my home to unwanted elements on the internet because they don't provide this safety net.   Sorry we all watched Westpac last week, will Optus be next week with their roll-out of modems that don't have the appropriate controls in place. 

So Optus, how do I change the DNS.  If this is not possible does it take a case to go to the ombudsman to raise that Optus is enforcing through their devices the promotion of porn to minors? 

Ok this is a bit sensationalised but need to do what it takes to get this addressed quickly as many people are complaining about the access on this modem and it does have consequences when things like this happen.

Getting my new modem and reading the impossibility it is to changing a DNS (this should be standard access folks) and limiting tools that should be possible as a parent to protect children.  I'm not against adult sites for adults, just don't like it when I can't limit minors from getting exposed to it.  Not sure if this needs the ombudsman to act on it - but trying here first.

Still no word at this stage. I have raised this question with our Network engineering team. 


From my own personal experience, I've never owned an Optus supplied modem which allows you to set a custom DNS from the modem. It's always been a feature that's locked down.


The team has mentioned that they're making an assessment on the security implications of allowing customers to set a custom DNS from the modem settings page, but I haven't heard much talk of it since. 


You can change the DNS on a individual device level. There's a great guide up on howtogeek

Thanks Dan C
Sadly this was available on the cable Netgear modem supplied by Optus before moving to the NBN - hence the issue with the new modem. If anyone could recommend a device that works from Optus as a replacement that works with has phone capability and isn't $$$ it would assist.

Re: Setting DNS to block porn site using Sagemcom FAST5366TN-A

Hi @Dan_C 

Any news on this or is there an alternative modem that I can purchase that can bypass the Optus DNS settings.  In reading some of the forums it seems that even if you do setup an alternative network the Optus modem still hijacks the DNS settings.

Given our household is exposed to many unsavoury things on the internet - I'm getting to the stage where I need to ask if I am able to cancel my contract with no penalty and go to an alternative provider - given that I now have a worst outcome than what I had when I was on cable.  Several of the other NBN service providers do not lock the DNS, thus would allow me to use my openDNS parental settings.  I've been with Optus for a seriously long time including my mobiles, but the lack of action on this issue is very sad and not what I would consider to be in line with child protection policies that families need.

I also would like the solution to this and will be raising the same issue for Optus modems as well. the netgear modems had more control over internet traffic.

Re: Setting DNS to block porn site using Sagemcom FAST5366TN-A

I have a similar story. I recently also was moved to the F@ST5366TN-A about a week ago. I used to be able to configure my Netgear CG3000 to suit. Now many options on the 5366 are greyed out. DNS being one, which previously was available.

After setting it up and playing with it for an hour or so I'm not asking for much:

1. I'd like to change the login username for instance. I find it hard to believe everyone who owns a F@ST5366TN *must* have 'optus' as the login username. The username field has been greyed out and cannot be changed. Wierd.

2. Similar to number 1 the default device name is 'my gateway' and the field to change this is greyed out. Again everyone who has this device must have 'my gateway' as the device name. Why? Let me rename it.

3. As above, I'd also like to assign my own DNS. Currently it is unchangeable from 192.168.0.1.

4. Lastly, I would like to be able to assign a device name against each MAC address I enter when I activate MAC filtering for my wireless devices. At first glance it looks like you can as there is a 'device name' field in the list, but you cannot actually edit into it. Its hard to tell which device is which when all you can see is strings of hex codes. (Although admit this was the same with the 3864).

Not sure why these really really basic settings are locked out or just not available on what is a brand new device. None of these would break any kind of policy. They are really personal preferences.

BTW the device has updated itself to the latest firmware ending in 105.

Re: Setting DNS to block porn site using Sagemcom FAST5366TN-A

Short answer. Optus want to stop people "breaking" the service by having people make incorrect changes. Why? It has nothing to do with security. It reduces the number of support calls.

Users need to make changes to DNS, e.g. to block PORN form kids' computers.

To avoid this causing issues for Optus they could:

1. Open the modem up to allow those changes. Happy customers.

Customer rings up and says it's not working.... Factory reset! (hey. Don't they do this anyway?)

2. Even if Optus are paranoid, allow Customers to call and be given the admin password. Hey even get them to agree that if something goes wrong they have to do a factory reset before calling for support.

Let's put together a list of RSP / ISPs who do allow DNS changes on their modems:

Aussie BroadBand

Mate

Dodo

Exetel

Belong

........

 

Thanks Optus. Where do you want your Customers to go today?
