[ANSWERED] Site-to-Site (IPSEC) VPN between UTM 9.3 and Copernicus

Hi there,

I tried to establish a VPN Connection between a UTM 9.3 and Copernicus.

1. I defined a Policy that matches the AES256 PFS Policy on UTM 9.3 in Copernicus
2. I defined the other policy Settings for the VPN-Connection

After that the VPN-Connection was successfully established (according to UTM 9.3 and Copernicus)
But it's not possible to reach any host through the VPN-Connection.

Any ideas?

  • I was able to find the problem.

    I used the same Policy I normally use to Access the Internet.
    In that policy "Rewrite source address" was active.

    So the traffic was allowed but the source address was replaced by my public IP.
    That was reason it couldn't work.

    I now configured a new policy exclusively for VPN without masquerading.
    Now it works [:)]

    Thank you all for your assistance.
