Maintainer: @Andy2244 Environment: VirtualBox x86_64, OpenWrt 21.02.0 r16279-5cc0535800

Description: After successfully configuring softethervpn5-client using vpncmd, I try to connect it using AccountConnect <name>, and let OpenWrt to get IP using DHCP, I achieve network connectivity (ping -I vpn_wand 8.8.8.8 works), but after a minute the general protection fault appears in logread and connectivity is lost suddenly. All installed packages are up-to-date. I followed most of the steps mentioned here: SoftEther VPN Client

vpncmd commands ( are filled parameters):

NicCreate wand
AccountCreate test /SERVER:<hostname:port> /HUB:<hubname> /USERNAME:<username> /NICNAME:wand
AccountAnonymousSet test
AccountConnect test

Snippet of /etc/config/dhcp:

config dhcp 'wand'
        option interface 'wand'
        option ignore '1'
        list ra_flags 'none'

Snippet of /etc/config/network:

config interface 'wand'
        option proto 'dhcp'
        option device 'vpn_wand'
        option hostname '*'
        option metric '30'

Snippet of /etc/config/firewall:

        option output 'ACCEPT'
        option forward 'REJECT'
        option masq '1'
        option mtu_fix '1'
        list network 'wan'

In case this helps, I have uninstalled softethervpn5* packages and installed softethervpn* (4.34-9745-1), have applied the same steps to setup vpn connection and connected, so far did not face the same issue as in first post.

I initially thought you were on 22.x, where I'm also having issues, but in 21.x it has always worked well for me.

1) I assume you also have a network entry for config device option name 'vpn_wand'?

2) I only ever got mine working with an interface entry like

    option proto 'dhcp'
    option device 'vpn_xxx'
    option defaultroute '0'
    option delegate '0'

plus static routes for some IP ranges

openwrt / packages
