RS700 - passing L2TP traffic to internal server
[NOTE: I am preconfiguring an RS700 on my local LAN so I can send it to a remote family member. Hence, the "external" address of the RS700 is a private address (192.168.3.155); the LAN/internal addre...

I greatly appreciate the help everyone!
Following StephenB's comment about trying to forward Port 5000 (and 5001 for https administration), I neither worked. Doubtful that it would be a Netgear bug, I went down the path of starting from scratch with the network connectivity. The issue (please don't kill me) is that I had the Synology server connected (via ethernet) to both the 192.168.3.x and 192.168.10.x networks (multiple ethernet ports in the Synology). Once I disconnected the 192.168.3.x ethernet, everything worked as expected.
Thanks for your help! Apologies if this is a rookie mistake...

p.s. When the RS700 arrives at the final destination, it will depend on what ISP device the RS700 connects to. (one NAT or two)

It will be replacing an existing R7800 so I'm not expecting any issues as long as I can get the VPN connectivity working.

If you have the RS behind the R7800, try using the R7800 DMZ for the RS router in router mode.
Does the RS not work in place of the R7800?
Can you configure the RS router for AP mode, disable the wifi radios on the R7800 and see if the passing of L2TP traffic works in that configuration?

Thanks.
I'm configuring the RS700 offsite. The R7800 is onsite (a full day drive away) and working properly. Once the RS700 is configured it will replace the R7800. The configurations of both appear to match (IP reservations, port forwarding settings, etc.). The only difference currently is the R7800 is connected to the Internet Modem while the RS700 is on a LAN in a lab.
R7800 config: Internet -> Modem -> R7800 (192.168.10.1) -> Synology (192.168.10.5)
RS700 config: Internet -> Modem -> Router (192.168.3.1) -> RS700 (ext. 192.168.3.155 / int. 192.168.10.1) -> Synology (192.168.10.5)
Test Client connection: Internet -> Modem -> Router (192.168.3.1) -> client machine (192.168.3.151) -> RS700 (ext. 192.168.3.155 / int. 192.168.10.1) -> SynologyTest (192.168.10.5)
My next move is to connect the RS700 to my modem (taking the 192.168.3.* network out of the equation) and testing from the internet.
