Problem creating the interfaces for a vpn on an FW 1800 splunk

[Luis1980]

To create a VPN in a FW splunk 1800 R80.20.20 Gaia embedded, because it is not possible to create the tunnel VPN interface and create alias interface with the same IPs, via web gives me an error and says that it already exists is addressing in my topology. Someone can help me. If not explained well I can send a screenshot.

thankss.

Item 1 - I would encourage an upgrade to a newer version e.g. R81.10.xx (or atleast R80.20.50)

Item 2 - Why are overlapping addresses / aliases required?

I will take into account the update.

Regarding the other question is how it is configured in the FW that will replace this

I understand that it is because of the issue of the peer so that it does not come out with private IP. But I'm not sure, it was already set up like this.

If you need a different IP address for VPN purposes, you need to configure it here (versus create an alias interface):

Otherwise, please provide more details about your existing configuration and the desired configuration.
