vpn site to site

damianodec

hi,
I need a VPN site to site, site A and B have USG40.
site A 192.168.6.x and USG40 192.168.6.254
site B 192.168.6.x and USG40 192.168.6.1

is it possible or have I to change addresses on A or B ?

thank you

Alfonso

Hi @damianodec

I do not think you can establish a VPN using yje same source and destination ip address range (I am assuming network netmask is /24).
If ip address range of the sites are not overlapped, the VPN be configured.

Another way to try to connect is to configure static NATs which will be done in (for example) in site A, and "undone" in site B. But i do not recommend it.

Check this article to avoid local subnet overlapping problem. 

However, it could be managed easier if the network with different subnet.

If you subnet each site to 255.255.255.128 then it would work.
