IPSEC - with same LAN on both end tunnel

[fastwrite]

Hi there.

I can't be the only one in the universe with this problem (i have searched and searched…)

We have a LAN range: 192.168.5.0/24

I have setup an IPSEC with gateway (the other ends wan ip - not the real ip) 172.16.10.20

The tunnel is up and running

THE PROBLEM

is that the other end is using the SAME LAN RANGE! 192.168.5.0/24.

I know that Cisco is using SAT to overcome this situation. But how do we do it with Pfsense on the one side and a Juniper on the other? On the other end, i have to ping a range 192.168.6.0/24 - which i can't, beacuse it seems that the routning is never leaved from the pfsense when i ie. try ping 192.168.6.10

Hope i have made my self clear.. - English is not my native language.

with regards
Thomas

This isn't possible with pfsense.

Re-IP one of the sites.  How hard could it be?
