I have this scenario, where I'm using XG as Gateway and have 2 ISPs connected on WAN Ports. 1 of these ISP (ISP2) is FTTH Broadband subscription. I have configured IPSec Tunnel to connect to HO, which is working fine with ISP1.
Now ISP2 have assigned a Static IP to us, but they are not ready to configure their ONT device into bridge mode so that I can get the Static Public IP on Firewall WAN Port. Currently I'm getting Private IP on Firewall WAN Port, so the gateway IP to ISP is ONTs private IP address. I want to configure IPSec Tunnel on this, which is not possible without Public Static IP Address. Any Ideas on this would help me retain the ISP or have to change the ISP2.
