Site to Site between FTD and VPN headend with Dynamic IP

[Gerald74]

Hello everyone,

I am trying to configure Site-to-Site VPNs as below:

Site A:

FTD v6.7  In/Out Static IP

Site B:

Modem external interface FQDN "my.exemple.com (IP 93.229.6.x it always changes)" - internal interface DHCP 192.168.178.0/24

FTD v6.7 receives for external interface from Modem IP 192.168.178.0/24.

See picture below.

I tried several configurations, nothing works, because external IP 93.229.... from Modem it always changes.

Thanks very much for your help

Dear Geralt,

You must use dynamic DNS services if you don't have static IP address.

Using ddns instead of public IP address is the best free solution.

Thank you
