Network Testing Troubleshooting PPPoSSH client This article relies on the following: Accessing web interface / command-line interface Managing configs / packages / services / logs Introduction This how-to describes the method for setting up PPPoSSH client on OpenWrt. Follow PPPoSSH server for server setup and PPPoSSH extras for additional tuning. Goals Encrypt your internet connection to enforce security and privacy. Prevent traffic leaks and spoofing on the client side. Bypass regional restrictions using commercial providers. Escape client side content filters and internet censorship. Access your LAN services remotely without port forwarding. Command-line instructions 1. Preparation Install the required packages. Specify configuration parameters for VPN client. # Install packages opkg update opkg install pppossh # Configuration parameters VPN_IF="vpn" VPN_PORT="22" VPN_SERV="SERVER_ADDRESS" VPN_ADDR="192.168.9.2 192.168.9.1" VPN_USER="root" 2. Key management Generate and exchange keys between server and client. Set up key-based authentication. # Client private key VPN_KEY="/etc/dropbear/dropbear_ed25519_host_key" # Generate client public key dropbearkey -y -f ${VPN_KEY} \ | sed -n -e "/^ssh-\S*\s/p" > sshclient.pub # Server public key VPN_PUB="$(cat sshserver.pub)" # Configure PKI mkdir -p /root/.ssh cat << EOF >> /root/.ssh/known_hosts ${VPN_SERV} ${VPN_PUB% *} EOF cat << EOF >> /etc/sysupgrade.conf /root/.ssh EOF 3. Firewall Consider VPN network as public. Assign VPN interface to WAN zone to minimize firewall setup. # Configure firewall uci rename firewall.@zone[0]="lan" uci rename firewall.@zone[1]="wan" uci del_list firewall.wan.network="${VPN_IF}" uci add_list firewall.wan.network="${VPN_IF}" uci commit firewall service firewall restart 4. Network Set up VPN interface. # Configure network uci -q delete network.${VPN_IF} uci set network.${VPN_IF}="interface" uci set network.${VPN_IF}.proto="pppossh" uci set network.${VPN_IF}.server="${VPN_SERV}" uci set network.${VPN_IF}.port="${VPN_PORT}" uci set network.${VPN_IF}.ipaddr="${VPN_ADDR% *}" uci set network.${VPN_IF}.peeraddr="${VPN_ADDR#* }" uci set network.${VPN_IF}.sshuser="${VPN_USER}" uci add_list network.${VPN_IF}.identity="${VPN_KEY}" uci set network.${VPN_IF}.ipv6="1" uci commit network service network restart Configure dynamic connection if necessary. Testing Establish the VPN connection. Verify your routing with traceroute and traceroute6. traceroute openwrt.org traceroute6 openwrt.org Check your IP and DNS provider. ipleak.net dnsleaktest.com Troubleshooting Collect and analyze the following information. # Restart services service log restart; service network restart; sleep 10 # Log and status logread -e netifd -e pppd # Runtime configuration pgrep -f -a ssh; pgrep -f -a pppd ip address show; ip route show table all ip rule show; ip -6 rule show; nft list ruleset ssh -i ${VPN_KEY} -p ${VPN_PORT} \ ${VPN_USER}@${VPN_SERV} ubus call system board # Persistent configuration uci show network; uci show firewall This website uses cookies.
