Problems with Portable Client and Arch-Linux

[methanatmer 0]

Hello everybody, Maybe somebody can support me here. I am trying to get the whole thing running with the original Portable Linux Client of AirVPN. After I had the "net-tools" installed, the tool establishes a connection to AirVPN, but breaks the connection after a few moments, since no DNS server can be found. Of course, I have already researched the topic and found some tips that point to the DNS server "nameserver 10.4.0.1" to write to the file "/etc/resolv.conf". Since this file is always overwritten again, I had the file with "sudo chattr + i /etc/resolv.conf" protected and so the new DNS server actually remained in the 1.Line. But also the tool does not find a DNS server. My other system then synonymous only again, if the new DNS server again disappears.

Does someone have you an idea how I get that running?
