Home firewall and server / modem mode + ip changes

Go to solution

I am shopping around for deals and looking at BT.

 

Currently we have Virgin which does modem only mode and the IP changes not even yearly on consumer.

 

I have a proper firewall which does routing and that feeds into a mail server - not business.

 

Can the new hub do modem only or something else, and if you dont unplug it how often does ip change please?

The BT hubs do not have a modem only mode I'm afraid. Openreach modems are available from the well known auction site. With an Openreach modem and stable connection IP changes will be rare.

Can you simply buy one, put password in and use as modem only? Will speed be up to 5*mbps as mentioned for stnd?

Yes, they are plug and play, user name and password are provided by the router at the PPP layer, not the modem and are generic in any case.

BT chat person says IP changes as done by exchange not modem.

 

For just smart hub is there a way of making it work with a business grade utm firewall please?

Obviously, BT supply dynamic IP addresses but as long as you don't disconnect the line the IP address shouldn't change. If you need a static IP address you need a business line.

You can connect it to whatever you like, but it will be performing the NAT and PPP functions and cannot be used as a pure modem.

If you decide to buy an Openreach modem, get the Huawei HG612 version in preference to the ECI.

I never unplug or turn it off. I guess if BT went down in the area it may change. If the line quality was poor it may re-set I assume.

 

Firewall wise I could turn nat off on it. Can you turn off dchp?

You can turn off DHCP but doubt NAT, I don't use a Home Hub so can't check. The Home Hub will definitely cause IP changes as it re-boots every 14 days and BT tinker with the firmware.

Ahh, the stnd hub reboots by itself and OpenReach does not?
