OpenVPN client has not default gateway when connect to OpenVPN server

sailershen · 01-24-2006, 09:40 AM

when OpenVPN client(Windows XP) connect to the server(Linux), the client has a new connect:

Code:

Ethernet adapter 3:

        Connection-specific DNS Suffix  . :
        IP Address. . . . . . . . . . . . : 10.8.0.2
        Subnet Mask . . . . . . . . . . . : 255.255.255.0
        Default Gateway . . . . . . . . . :

In the server there are a tap device:

Code:

tap0      Link encap:Ethernet  HWaddr 00:FF:0C:A8:CE:32
          inet addr:10.8.0.1  Bcast:10.8.0.255  Mask:255.255.255.0
          inet6 addr: fe80::2ff:cff:fea8:ce32/64 Scopeink
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:80 errors:0 dropped:0 overruns:0 frame:0
          TX packets:57 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:10082 (9.8 Kb)  TX bytes:7439 (7.2 Kb)

After the client connect to server, I cannot access the host on 10.8.0.0 subnet, I don't know why?

It's the server side configure file:

Code:

    local 192.168.123.153

    port 1194

    proto tcp

    dev tap

    ca ca.crt
    cert server.crt
    key server.key

    dh dh1024.pem

    server 10.8.0.0 255.255.255.0

    ifconfig-pool-persist ipp.txt

    keepalive 10 120

    tls-auth ta.key 0

    comp-lzo

    persist-key
    persist-tun

    status openvpn-status.log

    log openvpn.log
    log-append openvpn.log

    verb 9

It's the client side configure file:

Code:

    client

    dev tap
    ;dev tun

    ;proto udp

    remote sailer.gnway.net 1194

    resolv-retry infinite

    nobind

    persist-key
    persist-tun

    ca ca.crt
    cert client.crt
    key client.key

    tls-auth ta.key 1

    comp-lzo

Can the client get to the server? If so then the VPN is working. The 10.8.0.0 thing is just the IP addresses of the tunnel, ie. the virtual connection between the client on the server. If you have other machines connected to the client they should be on a different network - don't put them on the 10.8.0.0 network otherwise it'll stuff up.

Try this server config.

local 192.168.123.153

port 1194

proto tcp

dev tap

ca ca.crt
cert server.crt
key server.key

dh dh1024.pem

# old ip (same ip as your Tap)
# server 10.8.0.0 255.255.255.0
server 10.8.0.1 255.255.255.0

# IF you want your all of your clients traffic though your vpn out your connection then add this.

push redirect-gateway 10.8.0.1

ifconfig-pool-persist ipp.txt

keepalive 10 120

tls-auth ta.key 0

comp-lzo

persist-key
persist-tun

status openvpn-status.log

log openvpn.log
log-append openvpn.log

After that restart your vpn and connect your client. Let me know if it fixes your problem. Thanks
