5. If you are setting up a server, we suggest you run zjunet wlan disable to disable WLAN capability.

Download .opk package from Release Page (onto your router), Run opkg install ./zjunet_<version>_all.opk.

Simply run yay zjunet to build the package from AUR and install it.

Keep in mind that a fresh install without internet connection is almost impossible. Please complete installation before connecting to the intranet.

xl2tpd -v; curl -V; dig -v # Check installation of dependencies. There should be 3 version numbers.
# Under proper directory
git clone https://github.com/QSCTech/zjunet.git
cd zjunet
sudo ./install.sh
# If update is necessary, run `git pull` and `sudo ./install.sh`
# If you are setting up a server, we suggest you run `zjunet wlan disable` to disable WLAN capability.

ATTENTION Requirement check will NOT be done running ./install.sh. Please run xl2tpd -v, curl -V and dig -v to verify the installation.

This is a known issue. When overlapping VPN and ZJUWLAN, network packet may be lost. (because of nexthop in routing table).

Contributions to this issue are welcomed. (Maybe using iptables)

Set lcp-echo-failure larger in /etc/ppp/options.
