Duplicated IP for different Users

Hi team

I'm currently having an issue with GLOBAL PROTECT VPN users whose IP has been duplicated, as showed in the next picture:

As you can see, there is no big time difference between the log generated for the user sprbun\johnfc and the user sprbun\norac

I have configured two gateways and this problem is happening when two different users (like in this case) are connected to different gateways. This situation has become regular.

When the problem was occurring, I checked the ip asigned to each user from cli with these commands:

show global-protect-gateway current-user

show user ip-user-mapping all

and this is the information that I see:

From remote users in the gateway this is what I see:

I don´t know what could it be, if you could suggest me some troubleshooting guide or any advice I would appreciate it.

Thanks.

Hi!

If I understand your issue correctly, you're using the same IP pool on both gateways?

Its best to use a different pool on each gateway else you'll inevitably run into IP conflicts like you illustrate in your post (pool usage is not synced between the gateways, they're treated as independent 'networks')
