RV325 - Custom Service Protocol

[JThomas206]

I'm configuring L2TP VPN using a Windows 2012 server.  I know I can create custom services for the TCP and UDP ports but I can't see how to create a custom service for protocol 50. (Allows IPsec Encapsulating Security Payload (ESP) traffic to the VPN server.)

From MSFT: Configure a Firewall for VPN Traffic

I am able to create custom services on my older rv180 by selecting 'other' from the protocol drop down but I don't have that option on the rv325. Is this currently supported on the rv325? 

thanks in advance

Hi

Please go to setup -> Forwarding -> Port Range Forwarding -> service management then add the ports what you need.

Thank you for the reply Ami.  However, that is not the solution.  What you describe is how to forward a TCP/UDP Port.  Specifically, what I am looking for is how to forward a Protocol.  

(Here's a quick item on the difference between Ports and Protocols - What is Protocol 50 )

Protocol 50 (ESP - Encap Security Payload) is necessary to support  L2TP VPN.

On my older RV180W (past EOL) this is what the custom service drop down looks like.  Note that I can select 'Other' and define the Protocol.

Is this (or will it be) available on the RV320/RV325?

My mistake, I think there's no option to setup IP protocol on RV325. Have you encountered any problems?.

VPN passthrough does not configure the necessary WAN to LAN routing.  So, yes I have encountered a problem.  The problem is that I can't use my internal RRAS server to establish a VPN because I can't pass the necessary traffic though the firewall.
