On NAT channel, SRCNAT you need have the rule involving interesting traffic (local LAN subnets for example) before NAT masquerade. You can check logs if you want to troubleshoot. It may be that you don’t need all these ports, but you can close them later. On INPUT channel allow the following on the interface facing Internet You need to be sure that at least the IPsec packets are able to be accepted inbound on the WAN interface, so the below rules needs to be placed before the rule dropping packets (the Firewal rules are checked top-down) Mikrotik Configurationīy default, the Mikrotik comes with the INPUT channel that drop the connection incoming on ether1-gateway (which is the WAN interface). In this way the below configuration will be easier to understand. The red line represent the IPsec VPN tunnel. I did test the entire construct in GNS3 integrated with Mikrotik. For today, I will replace the Linux device with a Cisco.

I had a look around the net to work out how to do this and most decent articles are written using the older versions of the ASDM, and the CLI information I found on Cisco’s site didn’t help either.ġ. Note: If you want to use PPTP you can still terminate PPTP VPNs on a Windows server, if you enable PPTP and GRE Passthrough on the ASA.īut if you want to use the native Windows VPN client you can still use L2TP over IPSEC. When Cisco released version 7 of the operating system for PIX/ ASA they dropped support for the firewall acting as a PPTP VPN device. Note: This is for Cisco ASA 5500, 5500-x, and Cisco Firepower devices running ASA Code.
