VPN IPSEC TRANLATION ADDRESS

 


Hello, I do not know how, on our old ARKOON, we had an ipsec VPN between us and a provider.
Our LAN network is 192.168.100.0
The provider already had a vpn at another client using the LAN 192.168.100.0 network.
On the ARKOON, a network address translation had been implemented as in the photo.

The translated LAN is 10 .127.1.0
How to do on the sophos? thank you in advance

  • Salut and welcome to the UTM Community!

    I'm not sure what the ARKOON does nor how your provider manages this, so I'll have to guess.  Does the following work for you?

    • Create an IPsec Connection with 10.127.1.0/24 in 'Local Networks' and do not select 'Strict routing'
    • Add a NAT rule '1:1 NAT : {remote network} -> Any -> {10.127.1.0/24} : Map destination to {192.168.100.0/24}'
    • Add a NAT rule '1:1 NAT : {192.168.100.0/24} -> Any -> {remote network} : Map source to {10.127.1.0/24}'

    Cheers - Bob
