Instructions for installing "ASUSWRT by Merlin" on ASUS routers

You should already own an ASUS router with the standard operating system ASUSWRT.

The integration of OpenVPN is different than the original and seems more complicated. The PP OpenVPN However, configuration files assume the most important part of the configuration independently.

  1. After an openVPN If you want to establish a connection and have come to the right page, you can select the predefined area (client 1, client 2, client 3, client 4, client 5). These predefined storage locations can come with different VPNConnections are occupied.
  2. Get the right openVPN Configuration file from Perfect-Privacy VPN.
    You choose the OpenVPN Configurations of here.
    You can choose individual servers, servers as a group and in UDP or also as TCP. All versions will work with the ASUS router. (UDP may be blocked by some ISPs but has shorter ping times, but that should be known.) From the PP side, routers (legacy) use files with CPC encryption.
  3. Invite the OVPNConfiguration high.
  4. Then your view will be renewed and the basic configurations have been discontinued. Actually you need now only "username & password" enter and you could already about
  5. Service state: connect / disconnect ON / OFF

How to do that I'll show here by example "two VPN Use connections at the same time:

  1. Just create a second connection (Client 1-5) and start it.
    In the overview, you can make sure that both run properly. (Important if you have already entered routing for the same devices, then there will be an IP conflict, so do not route any devices before, or make sure you do not get a device over VPN 1 and VPN want to be routed at the same time!)
