Currently we have 7 VC systems that have static NAT's to external IP's which register to a central cloud based management service so external parties dial into that and the meeting is hosted there. This works well but if we decide to scale up to having more VC systems it's going to use a lot of our external IP's. Is it possible to hide multiple internal VC's behind a single firewall/ip? We have checkpoint R80.10. Maybe we need to buy some kind of gatekeeper device to do this but would be good if checkpoint FW could handle this.
