When I change IP, I can no longer access the web application

RichardHill

So I had this working not so long ago but decided to restart it after I changed a few IP addresses and couldn't access it. So plugged monitor and keyboard into my box and selected the "factory reset" option.

So; my device has 4 network ports and I'm going to be using it like this:

Port 1 Management - LAN IP address (Currently 172.16.16.16).

Port 2 WiFi - LAN IP address (not configured yet, but will be).

Port 3 - LAN IP address (going to be LAN segment of my bridge).

Port 4 - WAN IP address (going to be WAN segment of my bridge).

 

So, off I pop and configure the bridge (disappointed this needs an IP BTW. Why can't it just be transparent like the name "transparent bridge" suggests). Then obviously want to change the IP address of my management port to the IP on my management LAN. Change that and I can no longer access to the console at all. From a direct Cat 5e cable, or when I connect it to my network. So I plug my monitor and keyboard back in and it seems to have the correct config.

Is there something I've missed here? Am I supposed to be doing something else too?

Either way it doesn't work and I'm beginning to think this "upgrade" from UTM9 to XG is actually nothing of the sort. It's been nothing but a pain the backside since I upgraded it.

 

Cheers for any help!

    Hi,

    a couple of questions?

    1/. why are you using a bridge, just personal curiosity?

    2/. why are you changing the IP address of your management port?

    3/. from what interface did you change the IP address of your management interface?

    4/. Did you assign your PC etc with a new IP address from the management port range?

    5/. when you login to the console and display the network settings what IP address does your management port show?

    Hi Ian,

    Thanks for getting back to me.

    1/. why are you using a bridge, just personal curiosity? 

    Because I've already got a router in place and this is to just sit behind it as a firewall/IDS and not route any traffic. I may eventually move it into the full router position and remove the RV320 that I'm currently using; but for now I just want to configure this as an extra layer of security.

    2/. why are you changing the IP address of your management port?

    Because my management LAN is already established and has a different IP range than the 172.* one. It's currently sitting on a subnet of the 192.168.0.0/24 range and I already have other things configured like ESXi etc.

    3/. from what interface did you change the IP address of your management interface?

    I changed the management IP address from the management interface. However I then proceeded to change my management laptop's (device used for configuration and connected to the management interface) IP address to an IP in the same subnet as the new IP of the management interface on the XG Firewall.

    Yep, see above. :)

    The management port shows the correct (new) interface.

     

    Hope this helps! :)

    In fact, ignore the Bridge mode stuff. I'm going to YOLO straight into making this my router/firewall.

    Hi Richard,

    the only question I didn't ask, was did you restart the XG after all the changes?

    Hi Ian,

    No I didn't because I couldn't re-connect to it after changing the IP address.

     

    Since changing to a non-bridged mode I can now access it from my LAN. The issue I have is it's not passing data; but that's a different question which I'll raise in a different thread.

     

    Cheers,
