SH4 in modem mode responding to 2 ips 192.168.100.1 and 192.168.0.1?

I noticed a problem with my SH4 in modem mode, it still responds / web ui loads on the 2 default lan ips? I've tried several factory resets but it's still the same? I have been trying to get a replacement via support web chat but rhe my virgin media app doesn't get past a your hub needs a reset.

I'm hoping VM staff read this and can arrange a replacement self install.

 

Thanks

its fine for the new hub to load the UI on them IP's as long as you get your WAN IP its fine

 Yeah that, i gathered. I should mentioned initially some web searching took me to other occurances of the same issue on the SH4 and it does sound like a fault with the Firmware that normally can be resolved with a factory reset but for devices that it doesn't resolve then its a HW swap job.  I only noticed the issue when one day I was too lazy to mess around with an old semi managed switch which still had its default IP which was unfortunately 192.168.0.1 which I wasnt able to reach as I kept hitting my SH4 which made me wonder as knowing I was in modem mode it should of only responded to 192.168.100.1 which also loaded.  Thanks for your reply though, yes it will work but its def not supposed to do this I'm just lucky I don't use any sort of MAC to IP bind spoofing detection on my Firewall or that could lead to some problems. I may just have to call the dreaded 150 number, as the web chat support channel seems to be difficult to access on purpose nowdays..

Yes, if your Router is not using the 192.168.0.xxx   IP range, the Hub 4 can be reached on both IP addresses.  This has been a known "feature" for quite some time.

surely its not supposed to do that, Im an IT engineer and ive never seen it before unless u add additional IPS to a nic.. but if modem mode uses 192.168.100.1 then why should it also respond to router mode ip 192.168.1.1??? i havent checked mac addresses yet but surely theres a fault.  FYI i did read about this online and people were saying i was a firmware fault??

fyi i dont use 192.168.0.1, also no past hubs had this issue leading me to believe articles online that its a firmware fault

That's not ideal but it shouldn't break anything.

No NIC has an IP in bridge mode but it's supposed to have the 100.1 bridge, no idea why it keeps the other address.

It’s been reported before and is not a problem.

If your LAN subnet is not 192.168.0.0 when any device sends out a request to 192.168.0.1 your own router correctly sends it out on the interface to the VM hub.

If your LAN subnet is 192.168.0.0 when any device sends out a request to 192.168.0.1 your own router if it is not on that address knows it’s the local LAN and will not forward it to the VM hub. 

As far as I know it has only been reported for the Hub4, but may happen on the Hub5.

granted it works, but the biggest problem is that the 2 ips mac addresses are different which for my scenario is causing major headaches,,,  Would it be possible to request a replacement Hub 5 now??

I use a 3rd party firewall with sh4 in modem mode but the IPS and conflict detection is whats causing big problems

It shouldn't cause any problem even if your LAN was 192.168.0.0/24 it will stay on your LAN side
