ArsalanAli Lv3Posted 22 Sep 2022 18:58

I have 52 sites connected through the SD Wan central manager, Some time in VPN Logs of HQ Firewall's I get the warning that " Subnet 172.16.32.0 255.255.240.0 is conflicting".
This is the subnet of HQ  Lan site
I want to troubleshoot that from which of the 52 site this subnet is conflicting

Conflicting issue occurs when you have same network on different interfaces which is not a good practice for routing or VPN etc. Check your all classless networks and assign IPs to VPN peers accordingly.

You can use third party IP Scanner appllication to check for IP conflicts.

It appears that you will need to reinstall the software as well as download all of its components.

The issue is IP subnet conflict. A VPN connection must not have the same subnet on both ends, so you must check this and change the subnet to resolve the issue.

Basically there is warning to the firewall that says that subnet is already use before you can configure or add subnet

You should have a record or a list of IPs on all of your network to monitor the conflict.
