DHCP subnet change?

I have the Actiontec M1424WR REV F firmware 20.10.7.

On advance tab->IP address distribution -> action

I need to change my home DHCP server start and end addresses to correspond to a particular IP subnet -- company tech support demands I use a company-owned subnet for my company computer on my home network.

XXX.XXX.255.0/24

When I try to change just the start and end address, I get an error message:

Start IP Address, End IP Address: The DHCP IP address range does not conform to the connection IP address and the DHCP subnet mask.

What does this mean? Can I make this change?

Yes ... that was essentially the suggestion that I made in my first post. Use a second router in NAT mode with the local segment addressed as whatever range the employer wanted. If you have a NAT router which can be configured in plain "router" mode without the NAT, you could also add a second segment -- the problem here however is that the ActionTEC doesn't always properly perform the NAT translation toward the internet on the second range (plus you have to add the static routes for the other segment, which while not difficult, can be confusing for some).

Installing it as a NAT router behind the ActionTEC would result in a double NAT scenario, but that's usually an issue for almost any scenario except those requiring UPnP features.

what subnet are you trying to change to?

The DHCP range you are trying to specify must be the same subnet you are defining. For example by default the subnet the actiontec is using is: 192.168.1.0/255.255.255.0

The DHCP range must be in 192.168.1.1-254

Do you subscribe to FIOS TV?

Try going to My Network > Network Connections > Full Status > Network (Home/Office) > Settings.

Set the Actiontec's IP there at xxx.xxx.255.1. Then set the range on the page where you were to start at xxx.xxx.255.2 and end at 255.24.

I think that'll work. Once that change takes you'd logon to the Actointec at the new IP: xxx.xxx.255.1. And save your configuration file before you try this change just in case it doesn't work. Smiley Wink

The subnet I want to use is not in the 192.168.XXX.XXX range. It is in range reserved to my employer. Are you saying that Verizon will not let me use a subnet outside of 192.168.1.0/254?

I do have TV as well as internet. Does that matter?

You can change the subnet to be something other than 192.168.10 but the TV does rely on the 192.168.1.x subnet in order to properly use all the features of the STB.

I'm sure someone can comment on what happens when you use something other than 192.168.1.x

I'm using 192.168.0.x. I have my Actiontec's Rev E IP set to 192.168.0.1 and all features on our TV's, STB's, , etc. work properly. Even caller ID on the TV's.

So it doesn't have to be the default of 192.168.1.x but I've never tried anything as different as what the OP seems to need. It can't hurt to try what I suggested though. You can always go back to the defaults.

Will remote DVR functionality work if the subnet is not 192.168.1.x? I know VOD and the guide will work with a different subnet, wasnt sure about remote DVR.

We use remote DVR all the time. My wife has the app on her iPhone and I use TV Central. No problems.
