Site-to-site subnets

Hi all,

 

Im trying to setup a site-to-site vpn between two 60E devices. On one end I finished the wizard without any problems, but on the other end I get some error regarding subnets (see pucture). But I dont see any conflicts my self. What can be wrong?

We need more information.

What are the configured subnets on the site with the error ?

There are non really. The internal interface looks like this

Or maybe there is...

 

 

There is a dmz on that net. is that something thats added by default? This is a brand new firewall and I havent added it myself. Can I just delete it?

The error should be obvious but the remote subnet  conflicts with a local subnet. Have you  ran thru and LOOK at all local subnets to see if any overlap?

You can just change the network number to something else you won't be using, i.e. 11.11.11.1/24. To make your life easier, you should always stray away from default IP addressing, so in the future you won't run across this again.

Your DMZ network is overlapping with your remote network.

 

Change the IP of the DMZ to 0.0.0.0/0 and disable it, when you don't need this interface.
