The meanings of each option are followings: L2TP Server Function (L2TP over IPsec) This function is for accepting VPN connections from iPhone, iPad, Android, and other smartphones, and built-in L2TP/IPsec VPN Client on Windows or Mac OS X. Enable it if you want to support one of these devices as VPN Client.
Ubiquiti ERL users can't connect to L2TP VPN - Networking Mar 27, 2020 Layer 2 Tunneling Protocol - Wikipedia In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself. Rather, it relies on an encryption protocol that … iptables rules to allow L2TP/IPSEC VPN behind firewall

VPN Tutorials: Example 5 - L2TP Road Warrior – Smoothwall Creating a firewall rule. For traffic to flow through the tunnel, you must create a firewall rule that allows traffic to be routed between the internal networks and the clients connecting via L2TP. This is done in the Network - Firewall section. For a bi-directional rule select both L2TP and the Internal interfaces in both incoming and outgoing L2TP VPN — L2TP Server Configuration | pfSense Documentation
Configure firewall rules for L2TP clients¶. Browse to Firewall > Rules and click the L2TP VPN tab. These rules control traffic from L2TP clients. Until a firewall rule has been added to allow traffic, all traffic initiated from connected L2TP clients will be blocked.
The firewall supports L2TP as defined in RFC 3931. Add a remote access connection; Clientless access. Allow users to access services and areas on your network such as remote desktops and file shares using only a browser, and without the need for additional plug-ins. Clientless access policies specify users (policy members) and bookmarks. Layer 2 Tunneling Protocol (L2TP) is a VPN tunneling protocol that allows remote clients to use the public IP network to securely communicate with private corporate network servers. L2TP uses PPP over UDP (port 1701) to tunnel the data. Firewall Mode Guidelines Supported only in routed firewall mode. There was an L2TP port triggering rule enabled, that I toggled on and off with no change; Verified the firewall on VPN server had an exclusion for L2TP, or that the firewall is off. (Firewall is off to reduce a layer of complexity, but it worked internally to begin with so I doubt that's the issue.) set firewall name WAN_LOCAL rule 40 description L2TP set firewall name WAN_LOCAL rule 40 destination port 1701 set firewall name WAN_LOCAL rule 40 log disable set firewall name WAN_LOCAL rule 40 protocol udp. set firewall name WAN_LOCAL rule 60 action accept set firewall name WAN_LOCAL rule 60 description IPSEC If you have just a single L2TP client, you can reduce the L2TP IP Pool to that specific IP and you should always get that IP address on the client. Otherwise, SonicWall will assign one of the IP addresses from the L2TP IP Pool. I would also like to add that the L2TP VPN is for remote access from client side to remote resources on the firewall. Go to VPN > L2TP (Remote Access) and click Add to add an L2TP connection. Complete the following image and then click Save. Click the red icon under the Active column to activate the connection. Once connected it will show up as green. Create a firewall rule. Go to Firewall, click Add Firewall Rule and select User/Network Rule. In computer networking, Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to provide privacy.
