How to check the conflicted subnet in SD Wan Central Manager

ArsalanAli Lv3Posted 2022-Sep-22 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.
Is this answer helpful?

The problem is IP subnet conflicting. One rule on a VPN connection is to not having the same subnet on each end so you must check it and change the subnet to solve the issue.

The conflict must be resolve first because it will affect the communication between different locations.

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