Hi Jason,
I tested a gateway-to-gateway VPN tunnel with 2 RV042 in this scenario:
One RV042 (let's say RV042-OFFICE) in the office with a one to one NAT on an IP public address, the RV042 has a static private IP address.
the other RV042 (RV042-HOME) at my home connected to my dummy ADSL router.
RV042-HOME received an inside dynamic IP address trhough DHCP. The ADSL router itself has an inside dynamic IP address (not public), because my ISP share one outside public IP address between several inside users. DDNS doesn't work with this kind of ISP.
in the RV042-OFFICE vpn configuration I used the static public IP address + an email adress as authentication for the local group setup. dynamic IP address + an email address for the remote group setup. I also flagged the "keep alive" check box.
in the RV042-HOME vpn configuraion I set dynamic IP address + email for the local group setup, the static public IP address + email for the remot group setup. I flagged the "keep alive" as well.
it works without using the DYNDNS.
I did this test because my customer wants to connect about 1500 little branches (each of them has an ADSL access to internet) to a single center through VPN connections.
He likes this solution, but he doesn't want to use several RV042 at the center, but he prefers one or few VPN concentrators, not 30 of them.
HERE MY QUESTION:
Does someone know any VPN concentrator that accepts at least 500 VPNs, works with the RV042, where the RV042 is the initiator, has a dynamic IP address and cannot use DDNS?
thanks
Giacomo
