If you already have Softether installed on your server but want to update it to the latest version you can use the install code. the script now makes a backup, update, and restore your backup. but is more safe to do it Manual or just make a backup with Softether Windows software.

sudo systemctl stop softether-vpnserver.service

sudo cp /opt/vpnserver/vpn_server.config /opt/vpnserver/vpn_server.config.bak

wget -O se-install https://raw.githubusercontent.com/ipmartnetwork/Softether-easyinstaller/main/install-ubuntu-inteloramd.bash  && chmod +x se-install && ./se-install

wget -O se-install https://raw.githubusercontent.com/ipmartnetwork/Softether-easyinstaller/main/install-ubuntu-arms.bash  && chmod +x se-install && ./se-install

sudo cp /opt/vpnserver/vpn_server.config.bak /opt/vpnserver/vpn_server.config

sudo systemctl restart softether-vpnserver

now you can disable DDns from auto-installer disable DDns(Dynamic DNS)

sed -i 's/bool Disabled false/bool Disabled true/g' /opt/softether/vpn_server.config

sed -i 's/bool DisableNatTraversal false/bool DisableNatTraversal true/g' /opt/softether/vpn_server.config

sudo systemctl restart softether-vpnserver

If you have a domain, you must configure the certificate as follows in Softether Settings:

vpmcmd (if vpmcmd not work reboot your linux server and try it again)
 you server password
 ServerCertSet
 /etc/letsencrypt/live/YourDomainName/fullchain.pem
 /etc/letsencrypt/live/YourDomainName/privkey.pem
 exit
 sudo systemctl restart softether-vpnserver

It is not advised that you remove the log, although you may do so:

cd .. && cd opt/softether && rm -r packet_log security_log server_log

For SoftEtherVPN setting : just type vpncmd in the Linux terminal

vpncmd

To reset client traffic:

wget -O se-install https://raw.githubusercontent.com/ipmartnetwork/Softether-easyinstaller/main/reset-traffic-bbr.bash  && chmod +x se-install && ./se-install
