NAT PPTP VPN

Hello, im trying to set up a NAT rule for a PPTP VPN tunnel.

I have set it up like this:

Source: untrust

Dest. zone: untrust

Source address: Any

Dest. address: lets say 20.20.20.20/32

Service: any

Source Translation: None

Dest-Translation:20.20.20.20/32

Security Rule

Zone:untrust

Source address: Geo Location:NO,EU

Destionation:20.20.20.20/32

Application: PPTP(iv tried this and..)

Service: tcp-1723.

I can see in the traffic in the traffic logs, so there are signs of the traffic.

This is the logs from the PPTP server/router:

What are you trying to NAT? The description has the same destination translation as destination address.
