5. Re: OpenVPN issue

Re: OpenVPN issue

  • B

    Hoping I'm posting this in the right area.

    I used the wizard, created the certificates, created a user, exported the package, and the openVPN connects, however I can't ping anything on the other end?
    The wizard created 2 rules in the firewall, but I also tried disabling the firewall.

    My openvpn server config is as follows -
    Server mode - Remote access (SSL/TLS + user auth)
    Backend for auth - Local (I'd like to go to LDAP/Active Directory though)
    Protocol - UDP
    Interface - WAN
    Local port - 1194
    TLS auth is checked, with the TLS 2048bit static key in the box
    Peer + Server certificates are selected as the ones I created in the wizard
    DH Param length - 1024 bits
    Encryption alg - AES-128-CBC (128-bit)

    Tunnel network - 10.1.0.0/16
    Redirect gateway - disabled
    Local network - 172.16.0.0/16
    Concurrent connections - 30
    Compression - off
    TOS - off
    inter-client communication - on
    Dynamic IP - on
    Address pool - on
    DNS Default domain - on / myADdomain.com
    DNS Servers - on / intDNSserver1, intDNSserver2
    NTP Server - off
    NetBIOS - off
    Advanced - empty

    Here's the status log from the client side -

    Thank you for any help!

    as an aside - I'm switching to pfsense from Untangle, mainly for the multi-wan ability, so I setup openVPN on untangle before and it worked great.

    I split this off into its own topic, since it's really a separate issue and not a comment on the howto.

    It sounds like the client isn't getting the routes it needs. Did you set the "Local Network" for the OpenVPN server?

    If the client is on Vista/7, it should be run as Administrator, too.

    First, eliminate the doh! factor and ensure the firewall rules allow traffic from OpenVPN - it has it's own special tab that you need to allow any and all traffic through.

    If it's still not the issue, we need detailed logs, as it'd probably be a route that needs to be pushed by the server that isn't. To diagnose this, can you post:

    • the actual OpenVPN conf from the server - the file is in /var/etc/openvpn/openvpnX.conf where X is the ID in the address bar.
    • Add 'verb 5' to the client conf (advanced configuration) and post the log output from the client.
    • Mask out any sensitive IP addresses / domain names and post it here.

    @MrHorizontal:

    He already did that :-)

    The wizard created 2 rules in the firewall, but I also tried disabling the firewall.

    There is a checkbox in the wizard that adds the needed firewall rule(s) automatically to the WAN and OpenVPN tab.

    yes the local network is set, yes the openvpn tab of the firewall has a rule to allow all traffic.

    here's the server.conf file-

On the client I manually changed the dns servers of the openVPN interface to match the internal lan IP of pfsense and added a couple of test dns entries to the DNS forwarder on the pfsense gui, and the client gets those names, but here's a tracert on one of them -

[code]
C:\Documents and Settings\Administrator>tracert perforce

Tracing route to perforce.zg.com [172.16.0.100]
over a maximum of 30 hops:

  1    14 ms    16 ms    18 ms  10.1.0.1
  2     *        *        *     Request timed out.
  3     *        *        *     Request timed out.
  4     *        *        *     Request timed out.
  5     *        *        *     Request timed out.

  9     *        *        *     Request timed out.
 10     *        *        *     Request timed out.[/code]

so it's able to get the DNS record from the pfsense box when that is set as a DNS provider, but when I have the DNS provider set as one of my internal DNS servers, nothing.

Seems like nothing is getting past the pfsense box.[/i][/i][/i][/i][/i][/i][/i][/i][/i][/i][/i][/i][/i][/i][/i][/i]

    also, I can ping the pfsense LAN address from the ovpn client (a windows server 2003 box running at my house, just convenient because I can remote desktop into it to get this openvpn config working)

    and I can also connect to the webGUI on the pfsense box from that client.

    just seems anything past the pfsense box does not work.

    Is the pfSense box the gateway for the devices on LAN?

    @jimp:

    Is the pfSense box the gateway for the devices on LAN?

    no, at the moment I have this box setup along side our main gateway.

    all LAN devices gateway is 172.16.0.1

    this test box is 172.16.0.2

    Then that is why they can't get back. The traffic is going back to their gateway, not the pfSense box.

    So you can either:

    1. Change their gateway to the pfsense test box
    2. Put a static route for the client subnet (tunnel network) in the main router that will route that traffic to your test box's LAN IP.

    ahhh sonufa….

    I changed the gateway on my PC here and sure enough I'm able to ping it from the openvpn client.

    thanks that does make sense, didn't even think about that, so I'll chock this up as a successful test config.

    yeah, welcome to the dark art of OpenVPN's builtin routing table mangler! It took me nearly a week to figure out exactly what it was doing when I did the loadbalancing thing, but once you've got the hang of it, you can get OpenVPN to do the dirty work above and beyond its call of duty of just setting up an encrypted tunnel for you.

    As a basic crash course, for every tunnel, OVPN creates 2 gateways for each connection. In your case the local end of the tunnel is 10.1.0.6 and the server end of the tunnel is 10.1.0.5 (this is what 'topology net30' does in the PUSH REPLY message). The server then needs to hint to the client what the actual gateway is which also has to be in the 10.1.0.0/16 network (I assume this 10.1.0.1?), so it sets up a second gateway via a static route to 10.1.0.1 through 10.1.0.5. To route to 172.16.0.1 you need to add a third static route to the client so that it knows to send stuff to 172.16.0.0/12 through 10.1.0.1.

    Thankfully OVPN can do this for you and manage for the lifetime of the tunnel, so add:

    push "route 172.16.0.1 255.240.0.0 10.1.0.1"

    to the advanced box in the server page so that the client then pulls this and sets up the route.
