For L2TP, yes, you must open ESP and AH.. my firewall support only UDP Or TCP. I don't understand your statement. Does that mean your perimeter firewall only supports UDP? Or does your statement mean that it only supports TCP? Please clarify.. To add, I've never heard of a firewall that only supports either TCP or UDP.
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 Public server asks me to select a server type for which I chose other, then select the VPN L2TP service (I'm not sure if this is correct). It's protocol is L2TP(115) and the port range is 1-65535. Is a Public Server Wizard, you create a service group of all the ports you created for this server and then enter the IP address of the server. The last and most important piece to get this working is setting up the firewall rules for the WAN interface. I got stuck at this part and didn't realize there were two sets of ports that I needed to allow through for things to work correctly. Port 500 for Internet Key Exchange (IKE) UDP traffic and port 1701 for L2TP UDP traffic. Firewall: firewalld SElinux: enforcing IP address: 192.168.3.128. 1- Install L2TP. There is two common packages for linux to support l2tp protocol. one is StrongSwan and another is xl2tpd. here we install xl2tpd and related packages: # yum install epel-release # yum install xl2tpd libreswan 2- Configure Kernel parameters In the left menu, select L2TP/IPSEC. Click Lock. From the Enable L2TP list, select yes. In the L2TP Settings section, specify the following settings: L2TP Listen IP - The IP address that the L2TP/IPsec service will listen on, or in other words, the public IP address on the WAN which the L2TP client connects to.
If there are strict firewall policies, do not forget to add rules which accepts l2tp and ipsec. /ip firewall filter add chain=input protocol=udp port=1701,500,4500 add chain=input protocol=ipsec-esp Now router is ready to accept L2TP/IpSec client connections. L2TP/IpSec with static IPSec server setup Ipsec/L2TP behind NAT
