How to assign static IP on tap device automatically when each restart of the softether vpn service?
Currently, I need to execute ip command manually after each restart of the softether vpn server service.

Currently, in my startup script, the ip command is executed 4 seconds after the vpn server is started.
In the manual, bridge mode is suggested instead of using NAT. However, due to technical limitations, NAT is needed, is it a better idea to do NAT with tap device and iptables then using SecureNAT? I still use the SecureNAT function for DHCP and DNS forwarding.

You can simply configure your tap interface to use dhcp.
Since you are using uybuntu, modify the network config file /etc/network/interfaces:
!!!!
auto tap
iface tap inet dhcp
!!!!
